I need some help trying to decide which setup to use on a street car. I am running a 496 cubic inch out of a 400 block. I am running 11:1 compression with hand ported 440 stealth heads. I am going to use harland sharp rockers. I will be using stock manifolds with 2.5 exhaust. Should I use hydraulic flat tappet, solid flat tappet, hydraulic roller or solid roller? Also which is more reliable?
