I am experiencing the same rocker interference with a recently built and installed 327 in my 1978 truck. I've tried both tall and stock height cast aluminum with 5/16 cork gaskets with the same result. Witness spots show up on the intake side of the cover and the noise gets worse as the engine heats up. I am planning to try fabricated covers as they appear to provide significantly more clearance. If you would like, I'll let you know what happens.
