Jim,
I have the same setup as Mike above including the Crane roller rockers and I have had mine since 1996 with no problems. He is correct about the roller rocker clearance but I got Felpro laminated gaskets which gave me the extra clearnace needed for the rockers to clear the
oil splash shield instead of grinding the mounting studs down. All the laminated gaskets are is two thick ones fastened together with a steel shim in between. Never had a leak either, but either way is good.
