Yes (not I, though)
No. The only known Slant-6 head with what passed for a "fast-burn" chamber at the time was the mid-'70s US prototype aluminum head.

Too many people who were born on third base actually believe they've hit a triple.

One head is in the US.
Here is the chamber shape.

how did it get here? for sale?

Long journey, through a few hands, not for sale that I know of.
I do not have it.

when I look at that combustion chamber, I see a lot of valve shrouding
on a cylinder that is already constrained for valve size.

if we can go off of the engine info it was used on a 3.6 bore. i would love some measurements from this head - maybe a poured mold of the chamber side by side with a std head? is the guide c-c the same as a standard head? the thought of getting real info on that head is exciting. anyway does anybody have a thought on getting a pair of exh man to woody?

Last I knew the Argentinian head was in Minnesota. Current owner supposedly had it flowed and was underwhelmed at the numbers.

I have seen another head with welded up chambers like that. Last I knew it was on a Slant 6 record holding car.

well then. i think he should be disgusted and offer the head to any fool willing it give shipping money for it - like me.

does anyone have a thought about being able to get woody help on getting a good pattern price

Don't count on getting the head that is in the USA.
Start looking down south, way south to find another if you want one.

If I had manifolds I would offer them up.

Time to get Mike S energized and make a trip back to Oz and bring his back.

That was a huge bore!
I'm not sure that I would? Maybe to Doug or Lou or someone I know extremely well. They are just too rare to hand off to someone across the country or across the pond that I did not know.

The pattern maker that I had contact with are in my home town and have been for 30-40 years. They are supposedly some of the best on the East Coast.

Again the $5000 to get the first ones done is not the scary part for me. There are still a lot of what ifs that were my concern. What if I sold a bunch and they all cracked 6 month later....etc. That kind of stuff.

Now if someone said I will give you $2000 guarantee money to keep until my manifolds are returned, then maybe!

Any updates on the US Hyper Pak exhaust manifold repops?
I have spoken with Miks S a couple of times about his in OZ.
Not sure the status down under.

Still not enough interest in this? Seems like there should be enough slant sixers in the world to make this worth it....

We need 10-20 people who will pay ahead $500 each and wait 2 yrs to get their part. That takes legwork and trust. Go for it. I'm in for a pair, if I am confident the person doing it can get it done.
