You need something more precise than a measuring tape, like a caliper or mic.

Have the chambers CC'd. That will tell you how much they have been milled, and you will need to know what your compression ratio is, to accurately choose a cam.. Just about any automotive machine shop can do this, and you could even buy the tools yourself if you wanted to learn.

PTV really depends on your cam.. There are plenty of people that mill them to 59cc. Mine are 63cc, and im running AFRs 224/228 cam.. It may be on the small side, but im making 300RWTQ at about 3k RPM through an auto and stock manifolds/cats.

Cool,that was the same type of cam I believe I was looking at but I'll talk to a cam guy first n see what they recomend,thanks

60.5 cc will give you approximately 11.2-1 and you can easily run an upper 220's cam if not a bit larger with the right valve events.
