Im looking at getting a set of Proform valve covers for my car. Ill have AFR 220 heads and most likely T&D shaft mount rockers. Im wondering if anyone else has used these valve covers with 220s? How much taller than stock does the valve cover have to be in order to clear shaft mount rockers? The Proforms are only a 1/4 taller so im wondering if that is enough clearance? Any help appreciated,
Dan

My Proform fit my 190cc AFR heads with no problems. The alternator barely made it. Just needed minimum grinding. But they're tall enough, and taller than the stock covers.
