I'm just painting my Head with aluminum paint and calling it a day.
I'm pretty sure this train is on a continuous loop!

I used to make a lot of comments just like that one. It wasn't nice, no matter how right I was. Now I mostly just close the topic window and say "Not my problem, not my problem, not my problem" -- out loud if necessary so I'm sure to hear it.

409's got heads because there is a market for them and originals are worth too much to collectors to chop up for race heads. AMC got heads because there are 11ty billion of them running around in Jeeps. Except to a very small number of us Slants are neither race motors nor collectable. You want an alloy head? Get in touch with CNC Dude and offer to help him out. It's just that simple. |

All of the above is true and correct.

When 348s got new 409 rotating assemblies to convert the motor to a 409, the 348 boat anchors gained value. If you want a six cylinder part that would get lots of attention - in the wrong way, get this car, swap a twin turbo 2JZ and take it to the Mopar club race day event. Then, after it wins, open the hood. http://sanantonio.craigslist.org/cto/5127801107.html I'm not that interested in muscle cars, as I expect others on this forum agree. I read the magazines looking for new Hotchkiss suspension parts - which I can't afford anyway, but otherwise its the same old thing each month. 70 year old baby boomers own most of the muscle cars. I'm getting up in years too, but with this Roadrunner up on a rack and my Duster, you can't tell much difference with the motors out of the chassis. Same basic engineering, but one car when restored is worth $30,000 plus. I think CNC Dude isn't doing the head because the startup costs are about $50,000 and there isn't much enthusiasm for the design, which is more for drag racing than daily use. If a head is proposed that needs new manifolds, just do new manifolds for a well packaged turbo and keep the OEM head. |

When used very occasionaly these kind of remarks can be used to make an emphatic point. The trick is to use them as sparingly as possible.However....point taken. |

Well, the Dodge brothers did get started making parts for Ford...

Another pair of coppers ...... Other than for vanity's sake, I don't see anyone but actual nostalgia racers with cars below 1600 lbs. really hot for a light weight stock design head like the factory one. 30 to 40 lbs'd actually make a difference at that level. A non-stock design'd let us few out, so right off the bat there'd be a two camp division. Then, throwing in the puffer & port efi types, and the cross-flow boys, it'd bring it to at least three camps with divergent wants, even without a dohc voice being heard. So ...... develop three different heads, or market to a single faction of an already very limited market? I design product & tooling for small ceramic production businesses for a living, and would strongly advise any of my customers against a product that constrained. |

Well said. We have already reaped the benefit of market forces. Offy manifolds were designed 50 years ago when slants were plenty. Those same market forces will kill anyone who comes up with this mythical all purpose head now. |

Reality is, the Offy and Clifford intakes are still very hard to beat too. Look at how many hammerswingers have come on here and told us they were going to set the world on fire with their latest, greatest designs, and when really tested on a car, they were worse or at best equal to what Offy and Clifford did back then. Even Mike tested and fiddled with a Clifford and found very little improvement.The only way we will ever get a semi massed produced alloy head is if some reasonably wealthy individual comes along and does one out of the goodness of his heart. Sad reality is that the majority of the supposed "market" would disappear if such a head was actually available. I spoke with Howard Davis about the possibility of him doing more or selling a copy of his program to anyone else. That was not warmly received.

Many spend more than a $1,000 for just a set of wheels. You don't necessarily have to value aftermarket parts for any specific go fast benefit when a turbocharged Subaru would be quicker. This is a small niche market that does not map out to consumer prices ( does not necessarily make sense ). In the fifties aftermarket 12 port GMC six heads were built by more than one manufacturer and were slow sellers but they're still talked about. A few years ago a new batch sold for $4,500 each. One original producer of 12 port heads decided to use his skills to make parts for the aerospace industry where profits were much higher. Cheap one off old school methods can be used, along with CNC, but production numbers would be so low as to make the sales price pretty high. Each run might see "improvements" and variances with concerns for cracking and other defects might mean that the heads would get field tested for several years before buyers had confidence in the product. They'd sell for the novelty as much as any perceived performance benefits. If fewer than a dozen heads were produced they'd still be featured in most of the hot rod magazines. The inliners site was originally built around the 12 port head legend and it might be a reason that the slant six emphasized 12 ports as the OEM GM iinline sixes used siamezed intake ports to the end of production. Now, just finding a good GMC 302 block is a big deal for some. http://www.inliners.org/12_Port_Story/pt_six.html If the head looked great and had some performance benefits they'd trickle out to buyers and seem like a much bigger deal than they were. Like the cottage industries that made parts like this in the past, they were only marginally profitable at best, and were not designed by committees or group thinking. Most quietly went away when the small ads stopped appearing in the back of magazines, just as most of the publications went out of business. It'd be a labor of love - like all hot rods projects are, we should know better than to attempt justify this on common sense. We begin to sound like critics of old cars in the general public - it is not like selling tooth paste, makes so sense that someone would spend $3,000 on speciality parts, but folks like me have not made a new car payment in 22 years. A retired engineer with some free time might make parts, might get Jay Leno's attention, but few in the public would care. A labor of love, it would be like a heirloom that gets passed down. In the '60s Pontiac built a limited number of "Sprint" OHC conversions for the Chevy six, they're not that big of a deal today, quite affordable if you want one. A custom head for the slant six won't set the world on fire either, but it'd be kind of cool nonetheless. |

$1k for rims? Are you nuts? Last set of rims I bought cost me no more than $120. |

at this point, an aluminum head with a modern chamber and some improved ports would have the market cornered, small or not. it would sell to the guy who wanted a bolt on head or the guy building a racecar. the head is the weak link in terms of power on these motors, so if you have the only available upgrade, you are in. if you make a 4 valve cross flow head it might work better, but it wont sell to a guy who wants to get more fun out of his slant that just ate a valve. the guy who wants the 4 valve head will still likely buy your head because it still flows %30 or %40 better than stock, has some quench and he has no other options avalible
