Heads Studs vs. Head Bolts

My current engine has studs, it’s 11.2-1. The previous two were 10.8 and 11.4-1 and used ARP bolts. All three engines used Fel Pro 1008 head gaskets. IMO at my compression they’re all I need.

One thing I did on my current engine was after installing the heads I let it sit overnight. The next day I broke each nut loose and retorqued them. I did them one at a time, loosen then retorque, then move to the next one. Everyone of the nuts turned a 1/4 to 1/2 a turn farther on the retorque.

Was it necessary or did I accomplish anything? Probably not, but I found it interesting. BTW These studs were used on a previous build so they had already been stretched.
