Any one ever btrak the Cam Gear Bolts ?

My Pyle has this issue as of late. I keep breaking cam bolts. once with a timing chain and this go round with a Gear drive.

Im about to put some rounds in the Gen 6 502 BBC block.

The engine is a Gen 6 BBC with a 6 71 blower on it. Runs around 2 to 5 lbs of boost when Im semi on it. Never did hit full throttle. The engine is in a 21' Liberator pickle fork.

Im a bit frustrated. ARP says the cam gear should be Chamfered on the bolt holes. Ive looked at a few hi end timing sets and none have the bolt holes chamfered. Also the cam bolts arent shouldered. They are threaded all the way to the bottom of the hex head

I don't remember ever breaking bolts how do the cam bearing look and how much spring pressure
