Anyone have a recommendation for setting the valve lash on roller rockers with a Comp Cam that has a .389 lift? I readjusted them when I installed my new distributor and set the intake at .012 and the exhaust at .014 but I think I may have some too tight. That was on the recommendation of Comp Cams. The car runs fine when cool, after running for about 20 minutes on the road, the idle becomes erratic. Think it may be a valve set too tight. I plan on re-checking them all, but wanted to know if I should increase the gap.


Thanks,

Rono
