LS3 heads?
Hello guys. Will the LS3 heads bolt onto the LS2? If so, will the fast 102 also bolt on. I considered upgrading the heads, but realized how well the LS3 heads flow. Where could I purchase a pair and how much do they go for? Thanks

Yes, the L92/LS3 rectangular port aluminum heads will fit the LS2 very nice. The intake rockers for the LS3 are offset, so you will need 8 new rockers and a new rectangular port intake. You may also want to deck the heads slightly to increase compression.
Scoggin Dickey Chevrolet had the heads listed for $149 each last year, but they have gone up since then. They also have completely machined new heads with valves and .600" lift springs for $499.

Thanks, but I'd rather go new since they are a bargan and I only have 15,000 miles on my 06. $1700 for the set up is cheaper than a set of Trick flows. I figure with Spin's spec cam, Fast 102, ptb, headers, I should see 126-130 1/4 mph. I've been doing a lot of searching and it seems this set up produces simular 1/4 mile times as the TFS heads. Am I wrong?
