The casting from procomp are a decent enough casting. Where they get the bad reputation is their lack of final assembly skills. If you pull a procomp head apart and check clearenses you will see they vary a lot. For me, They are going in a marine application and sees high RPM for a long time. The procomp heads usually have a tight valve guide clearance. By the time you buy procomps and have them reworked to what I consisder is usable, you might as well buy darts/brodix/canfields/afr
