Depending on your cam selection and rocker arm arrangement your car will probably want a looser valve setting. Mine likes .035 on the intake and .028 on the exhaust. You need to run a good high pressure lubricated lifter to make them live. The lifters are the weak link. I check mine every race and if anything is loose the lifters need to be checked. Use a good quality oil and let the engine run at idle for a while before you rev it up. this proceedure has helped with extending my lifter life. Weak valve springs will kill your lifters as well.
