Line boring
Yes they will have studs in them before I pour the block filler. From what I know the OEM bolts are suppose to locate the caps better. I've heard of some people havig to drill the cap holes out to a hair larger size to make the caps fit right(with studs) but that was suppose to only happen if the holes drilled in the block were alittle off from factory. Also there is some play with the outer bolt holes compared to the bolts that go threw them so I will have alittle play room if I don't get it exact. Thanks for all the input.
