I have a set of ARP 12mm head studs that I want to install. I was reading where some people were having problems with studs corrosion over time. I think someone thought it was because of the studs cracking the block from installation. I always thought if the holes were clean and studs were hand-tightened, there would be no problems. Anything I need to know, when installing? Is there an update on installation instructions? Thanks.
