LS1 upgrades?
I have a 2001 LS1 and came across some heads for sale locally. They are LS2 heads for a GREAT price with only 300 miles on them.
My question would be what kind of performance increase could I see if I swapped heads and threw in a small cam?
I always wanted some LS6 heads but these are really priced nice and if they offer almost the same performance I might jump on them...
Thanks,
Mike.

LS2 heads are LS6 heads. They are the same casting. Sometime different numbers. the 02-04 LS6 heads have the special valves. Check the casting numbers either 243 or 799 if memory serves me right. Same flow rate.
