Heads: LS1-LS6-LS2?????
From the digging I've done, plenty of LS6 guys are getting 410-430 to the ground with a cam only swap, so what I'm considering is simply a swap to LS6 head along with a cam (in addition to bolt on's, ect).
But a thought struck me and I haven't found a really explanatory answer. When compared side by side, how do the LS1/LS6/LS2 heads stack up?? Are the LS2 the same castings as the LS6?? How about the manifold?
Thanks everyone.
