Ditch the six pac rods for a set of LYs with good bolts, or get a set of 440 Source I beams but budget to have them carefully checked and fixed.Stick a set of Stealths (if budget) or RPMS if you have the $$, I'd run a solid flat tappet something around 230°@.050 and call it done. Stock oil system, some sort of adjustable rockers..
