74 CB360 - Horrible compression after rebuild

Lapping isn't really done anymore. If your machinist is lapping your valves, they're doing it wrong.

Lapping is still done, apparently not everywhere, but I agree with ya about labor division. I would pay a machinist to machine not to lap. So forgive me, I misspoke, just wanted the OP to expand on what was done w the valves.
 
It's generally a bad idea to lap modern valves as the hardening isn't very deep and can 'wear through'
If seats are cut properly, you don't need to lap
 
Hey guys, sorry ive been MIA for a couple days, ive been super busy with work. Well i switched the cam around and compression was still low (40). I talked to a friend that owns a shop and he said to try to get it fired up to let the rings "set in". Threw some gas in, 2 kicks later, SHE LIVES!! Thanks for all the help guys i really appreciate it.
