4D55/6 ARP Head stud part numbers

[skullzaflare]

As far as I know the 4d56 do not use TTY head bolts. Do I have bad info?

i have had mixed results in my research, but a the same time 3 separate retorques i have had bolts come loose

Now to be fair i am running 2 turbos and 30 psi lol, i went through 2 headgaskets in less than a month, no issues since ARP

And we should be running the updated 4d56t head gaskets.
