And I can't tell any convex-ity of my lifters, I put a straight edge on it (them) and they look straight and flat. If they are really supposed to be convex and are now worn, does that mean the cam is worn too? In which case I say, nothing to lose, run it?

Whether you think you can or can't, you're right.

Also--in 2004, I invented the spotting alert network in stovebolt after seeing so many trucks when driving around. So that means I am cool.
