What is the difference in ARP and A1 head studs.
Thanks

Never heard of A1, you mean H1? A1 makes a great steak sauce though

To answer your ???, the H1 studs are made of some kind of steel that is harder than the ARP's. That's all I know though

ARPs are not as strong but not as expensive

the tinsel strength of the metal is higher

That price better include the install and some goodies or your getting ripped. Arp studs are only 600 max.

a1 technologies makes the h11 studs.

ARP's tensile strength is lower and will be just fine on the powerstroke as long as you don't over tighten the stud in the block or the fastener. Use twice as much moly as you think it needs, and do not use oil.
