what is the valve lash for B cam with original lifters?
Thanks

I don't remember the original specs. I think the intakes were around .012-.13" but the exhaust went to .022" after problems with burnt valves.

.012 & .014", no problems.

Different cam grinds require different clearances. If possible, consult with the people who ground the cam.

Also depends on the metal used to make the valves. Some expand more than others so need a wider clearance.
OP, Are you confused yet???

I thought Randall was asking about an original cam with original lifters.
