Default 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.

From what I am reading online they are from the 6.0l and have a larger combustion chamber. Not sure if they would increase performance or just make lower compression.
