I'm in the process of installing AFR Cylinder Heads on my Merlin 509 and the heads are threaded for two extra heads bolts on the intake/lifter valley side of the two cylinders on each side that don't have OEM bolts at that location. My block has the bosses to accomodate the two shorter head bolts from inside the lifter valley and I want to install them as it must be better for a blower motor to have the extra clamping in that area. (These bolts screw into the heads from inside the lifter valley)
The problem is, I can't find any articles or features in any of the Big Block Chevy literature I have on these bolts. Does anyone know what type of bolts are used and what torque specs, lubricant/threadlocker and what sequence is used on them?
I'm using an ARP stud kit and Fel-Pro Marine High-Performance Gaskets, if that matters.

I just installed those on mine. I think the studs were 1-1/2" long. AFR said to tourk to 35 ft lbs with lock tight.

Thanks.
