Arp Head studs or bolts Hey im in the process of building my lt1, im going 383 with forged eagle crank hbeam rods and mahle fully coated pistons. im also going with eagle 4bolt mains and arp studs. i wnt to go with arp head studs but the machine shop said i should go bolts. the reason they gave me was possible clearance problems and said they leak has anyone had problems with the studs?
Depending on your power goals stay with the bolts if you can. Studs leak on LT1's if not sealed properly. Do a search and you will see. I run studs but I have to with the power I have.
although i do agree stay with the bolts i dont understand why people cant get studs to seal. sealant on the stud and screw it in until it seats flush with the "shoulder". im assuming people do the finger tight method and some dont quite seat. granted i only have about 1k miles on motor but i have no seeping or leaking issues.

My block’s never been out of the car, let alone bored with a plate.
Studs allow you to make up the torque using fine threads with proper lube on them to get a more accurate torque reading. It’s better than getting your torque level from coarse threads coated with sealant into the block.
Installed correctly with good sealant on the block end there’s no reason studs should leak.
You should all get the book, "Carroll Smith's Nuts, Bolts, Fasteners and Plumbing Handbook" and live by it.
