The older engines/timing covers use 3/8-16 bolts with a 12 point small head. They are called Ferryman head bolts. It's possible the regular head bolts are not seating flat on the pump. Using pipe sealant with Teflon or aviation form a gasket on the bolts should seal that area as mentioned. Also it's possible the pump itself may be leaking oil from wear or poor manufacturer. If you need the correct bolts, PM me after you verify the thread size, 3/8 vs 5/16 and I will send you a couple for shipping cost.
