LS3 heads on LM7? I'm sure this has been asked before but after searching I couldn't find a definitive answer. I'm building a twin turbo LM7 and was looking at doing valvetrain upgrades. Instead of porting the LM7 heads, putting in new springs, retainers etc. I was thinking of just buying some of the Chevrolet performance heads since they come complete and ready to rock.

My question is the specs say they need a minimum 4.0 bore but the stock bore is 3.78 and this trucks. Will this work or will I run into problems?

I keep hearing about small bore LS3 heads. I don't know if they are aftermarket, or GM. Might look into that. Or put a 4.8L crank in a 6.0L block. Will give you a short stroke screamer. Or just use a 6.0L.
Looks like the small bore LS3 heads may be GM. Prob wont bolt to regular heads since they have 6 bolt configuration.
