273 cam suggestions

rumble rollers are the ****! but thats aloda coin for a 273, unless a real bad boy engine.

273 valve train sort of gift to LA engines set good it works within its limits (lift/lobe profiles) pince with roller? ;), after that roller is good specially with new **** oil regs,

have not used but is brad penn oil still going in the states? old school refinery have heard... any good oil for flat tappets over there?
