I'm putting 2.02" valves in 360 heads ...

I'm also planning on polishing up and removing the crests and edges in the chamber like in @krazykuda:s heads above. I might also deck them 1-2 mm (0.040 - 0.080) to get the CR up after doing that.

The head/gasket/piston combo I have right now (different 360 heads, untouched, casting # 578, these are 974) give me pretty darn close to 10.0 to one. I'm no expert but I might be able to get away with higher CR with a bigger cam, right?
