Just curious here, but what heads would one use to get about 9.5:1 CR on an LS1? 317's maybe? And what is the stock CR on an LS1?

I am going to save all of us a lot of trouble. Here is a compression calculator. Google can answer any questions you have about the information it asks for.Quote:

what are the stock values for that calculator playboy? :lol:
Now that's the kind of answer I was looking for. Thanks dude. BTW, which heads will get an LS1's CR a little higher than 9.2?Quote:

I'm still looking for the rest of the info the calculator calls for.Quote:

True. While I don't mind using different thickness gaskets, I'd like to avoid milling heads because I don't want to have to get different length pushrods.Quote:
