Ive been working at a machine shop for almost 2 years now and we don't get many Pontiacs this is the 2nd since ive been here. Its a 389 .030 over with 092 heads the customer wants roller rockers after the motor is already finished. Yesterday I took the heads off and pulled the studs out. Today I had the heads on the dcm machine and my boss told me we had to cut the stud bosses down and drill and tap the hole. well doing what he said Ive drilled into all the intake ports and 2 water ports in the center. My question is was it right by cutting the stud bosses down and we are using bbc studs and crane 1.65 rockers
