What is the torque spec. Didn’t see it provide paperwork 
I’m thinking 45-55
thanks

I use ARP head stud kits on my three Y blocks with no issues.   The longer bolts go in the head dowel hole location.  Here is the lower ARP studs on aluminum heads.  Joe-JDC

Joe, do you recommend ARP studs for iron "G" heads as well?

I prefer the studs since they have the fine threads under the nuts.  In my opinion, that gives a better torque value with a high pressure lubricant.  The ARP studs have an allen fitting in the stud to make it easy to install or remove them.  You simply loosen the nut a turn, and use an allen wrench or allen socket to remove the stud with the nut and washer in place.  The studs are installed in the block just hand tight, or tight and back off a quarter turn.  Joe-JDC

Did you buy your studs from Mummert? I didn't see a listing for Y-block head studs on ARP's website. 

Yes I did.
