head studs..Super C

What's the best way to torque the cylinder head studs? I was thinking double nuts on top? What's the torque spec? Should it be the same as the head nut? I got all the old ones out....they seemed really tight...tighter than what it was to get the nuts off...had to heat the block to get the studs out.

Head studs should be installed in the block finger tight with sealant I've always used Indian Head shellac compound for the sealant. If you torque the studs into the block there is a risk you could pull a thread up above the deck and cause a leak.
 
I would personally snug them in a little. I would say to 10 or 15 ft lbs or just a small little tug with a 1/2 in. ratchet. That way during a future removal if one of the nuts binds on the threads a little the stud just won?t screw out as easy. Any reason you pulled the studs out? Those studs are usually good for a couple lifetimes.

Here is a link to instructions from ARP for installing their head studs: https://arpinstructions.com/instructions/233-4601.pdf

The fine threads on top were in really bad shape...pitted and corroded...after I wire wheeled them they really looked terrible.
