Two of the aluminum blocks I used that came with the no name studs ended up needing them replaced.

On one of them they made it through the initial assembly, but several wouldn’t torque up on the first freshen up......... on the other block several wouldn’t torque up on the first attempt.

And that was using the tq spec from the paperwork that came with the block, which was lower than the ARP spec.
The side bolts looked like hardware store grade 8’s.
Junk hardware in a $5000(at the time) block.

The ARP’s higher tq spec required the blocks to be line honed to get the mains round again. Might be more of an issue with the aluminum block, but after replacing the studs, on one block the crank was quite hard to turn, and the other one tuned okay, but didn’t feel “right”........ so they got line honed(just more time and $$$).
