273 rocker arms
Shafts drilled A-OK with a new HSS bit, mine were toast. Could tell when it punched through the hardening. Found an interesting diagram of intake and exhaust lifters in a 65 FSM. Some proposed oil galleys in rocker arms based on intake or exhaust? I say proposed because I have never seen any gun drilled down the nose like these...are these 318 poly? Look a little long for 273...
