Slant Six Forum :: who's interested in an aluminum head?

i heard it would take at least $20K for 2 heads to get things started and around $3K for copies thereafter. what does it cost to have an old casting professionally cleaned, machined, new oversize valves fitted with new springs, guides installed and machined down for double valvesprings, threads chased/repaired, ported and flow tested? now how bad does that complete, lightweight, high flowing, revised/CNCd chambers/ports head sound?
in another conversation i learned a few racers coughed up a similar amount for billet crankshafts that were quite a bit stronger, but weighed the same. for the money, i'd rather buy a part that makes more power and saves 35 pounds. where are you going to find another 35 pounds to strip off your racecar without cutting out daily chicken biscuits and colbars? you going to go out and build another car to save the weight? i don't totally understand the resistance to the idea of a trick head for the slant.

I hope the 2 prior authors realize that the statement they made in jest ("...4 inch bore...") may be taken as a serious comment? All it would take would be a new head, block, crank, manifolds, cam, pan, valve cover, rocker shaft.. Wait - that's a different engine! Yes.

Yep....with a four inch bore, and the slant having a four-inch, center-to-center bore spacing, that would be kinda hard, wouldn't it? Roger

OK you be the first one to buy a 3000 dollar alluminun cylinder head and tell me how much it better it worked . Then i will buy one. Thanks Ron Parker PS 1000 dollars a head that is not what our research has come up with unless you could sell a thousand of them. New Year New Gear

I'm not interested in a race head, just a better performing one on a stock/mildly modified street/strip motor. Over 90% of the folks who would buy one want a bolt-on piece that provides more performance. If enough are pre-sold, the price would be resonable. All that's required is to raise the ports a little, improve the shape of the ports and chamber and it would outperform ANY modified iron head out of the box. Couple that with additional meat so that they CAN be ported for all-out racing. It wouldn't be hard to sell the idea to anyone who has priced out the cost of modifying their stock head.

Hell i got a all out racing head done for lets say 1000 bucks. You want me to pay 3000 dollars for a alluninum head that can non match my flow numbers on my steel head . Keep your hope up but it aint going to happen. Thanks Ron Parker New Year New Gear

Nobody would touch a $3000 head for a slant 6. It would have to be in the mid 1.5K range which is doable if enough people commit to buy one (ie - pay for it before it's actually made) prior to production. And just how do you figure a head with raised and improved ports and chambers would not out-flow the asthmatic and poorly designed OEM head? I've seen the numbers on ported stockers. They don't impress me and wouldn't be that hard to beat with a new head.

Why not pay $ 3000 for a head? Thats what the after market cranks cost!! The problem is you are only talking about 5 people that are at that level.

Don't think a good, emphasis on good, aluminum slant six head can be produced for $1000. If a $1000 slant head was available, I'd pass because most likely it would be a Chinese produced low quality head, or make that head-ache. An aluminum head project will never happen unless everyone is willing to spend at least $1500 for one. Look what the high volume Eldebrock BB Mopar heads cost, $650 each, and that is for only 4 cylinders. Other BB heads are $800-$1400 each, mostly due to the lower sales volume. The $3000 cranks wouldn't be $3000 if they could sell 100 of them.

$1800 would probably be a realistic price range. And BTW, you can get a billet crank for the /6 about $1500-$1800. Let me know if you're interested and I'll point you in the right direction.

i don't think $20k would be needed to initially build the head. my friend is taking foundry classes and was interested in doing this purely for the experiance and knowledge he would gain. the head would probably cost $1500-$2000. i know this would outflow mildly ported heads if not fully ported heads. look back at all the features that would be changed/included and i do not see the point to of keeping an iron head, especially if you want any kind of performance out your engine. this head may not be built soon, but when it is built, it will be worth every dollar spent on it. zedpapa

Cast a batch of heads and throw them on ebay! You're telling me the <fine people> who are willing to pay $250+ for a super six set-up wouldn't be willing to fork over $3K for a nice, shiny aluminum head? And there seem to be PLENTY of those folks, although they obviously don't frequent .org... VM

I prefer to keep playing with the iron stuff, much cheaper and that is what the slant is about for me. If I were thinking exotic I'd be looking for a M3 Bimmer motor to take the place of the slant.
