Another opinion question
Also check the guide to retainer clearence, this one area that gets over looked very offen and casues big problems. If running dual springs then check the inner spring for coil bind as this isn't seen either, but check it at full lift with 0 lash. The coils should have .060 or more to be safe. Not trying to alarm you just inform you so it will work right the first time, and this will make you feel better also.
