Can anyone tell me the best way to get quench from a 383 using the 906 heads? I looked at the Edelbrock closed chamber heads on Summit and I don't know if it was a misprint or what but it listed the bare 84cc heads for $900+ each. I think I want to use the 906 heads anyway, and if I don't like them I can always change things later on.

I'm not building a racing engine, just a nice street engine. I'm shooting for 375-400HP.

If it helps my other list of parts will be a Performer RPM, 750 carb (not sure which), XE 274 cam and matching springs, stock rockers, MP ignition, Dougs headers, and 2 1/2" exhaust. Not sure on the pistons, that depends on what you guys recommend for the 906's. The car also has a 727/3.23 SG set up.

Thanks

To the original question..
My thoughts, to get quench with a 906 and a .039 gasket , the piston would need a quench pad of around.120 height above deck.
On my street 383 I used .060 milled 516s with .080 in the hole pistons. It will not run on reg gas and makes somewhere around 425 hp. Its cheap and ez, works well. With my cam choice and 3.23s it needs to see 25-30mph before it turns on.
