Piston to valve clearance - How much do I need?

[Rick 91GT]

I agree with Jeff in take your measure ments on the outside of the eyebrow. Now I do have 2.02 valves but I had .139" clearance and after I got the motor apart I saw a slight mark where the valves had kissed the piston on the very, very edge of the eyebrow. Now since I fly cut them it is not a issue. I was always told .100 on the intake and exahaust as a min.

You can take some epoxy and fill a roller lifter or weld one shut to make a solid lifter.
