317 casting heads have a 72cc chamber..... that's your cheapest route
and so you can figure the actual static compression out...

I like my AFR 225's 72cc on my 346. Very nice flow throughout lift, not just at the top. Dished pistons are probably where you'll want to go to lower that CR.

OK, thanks for the answers...
With heads, what kind of boost/power can i make if the rest on the engine is stock?
Going to do more to the engine but that will happen later

keep an eye on the sales section. I got my 317 heads with 918 springs + titanium retainers for about 360$ shipped.
317 wont get u to 9:1 C/R . u will be at 9:4-9:5 c/r . I Just order a set of cometic custom gasket 0.065 thikness that will drop the c/r more. also doing some porting will lower ur C/R.

ask for the casting number.
the ls6 heads doesn't come with a 72cc unless he is talkin about the 317 casting (lq9). or if they r an aftermarket casting. so make sure.
