No roller tips. No bronze bushings in lifter bore or custom lifters (stock type hydraulic lifters only). ***** in studs and guide plates allowed. 120lb stock dia springs max, stainless valves 1.94 intake & 1.50 exhaust. No angle mill. Steel timing chain. Stock crank and rods. No 6" rods in GM motors. A.R.P Rod, crank and head bolts and studs are allowed. Claimer oil pan & maximum fluid damper allowed.
