best head studs?
#7
i am blowing out head gaskets at moderate boost and super safe tune, this is on my truck. 5.3 is running strong so far. i have some kind of problem with my set up right now. my first step is a fresh set of head studs but i was thinking about upgrading from the standard arp's.

Interested in this topic as going to be doing up new motor soon. I will never go past 20psi likely not past 15psi if go for lsx block 427 with afr 225 heads. I am keeping my fast 90 intake at least for now. So will I need these more expensive arp or a1 studs or will the regular arp with gm mls gaskets be enough?

i have taken the basic arp's with cometics to 18psi on the track and 22+psi on the dyno. above 18psi on the track and i start hurting things but i am not sure if my tune is optimized.
lately i can't even do 14psi so it seems i have hurt something or something is worn out.

block is iron, studs wouldn't pull out of that would they?
can you check the block deck with it in the truck still?

I seriously doubt you'd rip a L19 stud out of an iron block. I called ARP a long time ago about them and was going to recommend them to you in your other thread, but was banned. After talking to the ARP guy at the special order shop about them I plan on running them in my new engine. He quoted me $419+ S&H on them if I remember correctly.
