What do you think of these heads?
Ex.-210
Ls6 springs and seals, and a 3 angle valve job done w/ back cut done.
Going to get them this weekend and would like to hear everyones input on them.
also, i might as well get the Ls6 manifold while i got everything else taken off. anyone have a clue to what HP gain i might get?

check this out, here is a thread i was reading earlier what do you make of it?
I picked up 25 rwhp with hand ported heads (stock valves) running the stock cam and exhaust manifolds back in 1999. Headers were still coming on the scene at the time, as were cams. Later in 2000, guys who had long tubes picked up 40 rwhp by adding Stage 2 heads and keeping the stock cam. Once they found out they could gain another 40 rwhp by adding an aggressive cam, they did those too.
Thanks-justin
