4.0 sohc NON TTY cyl head bolt torque specs?

[Devan]

Im ditchin the factory cyl head stretch bolts for some grade 12 reusables for my supercharged 4.0 sohc and i was wondering if anybody had torque and tightening procedures for non tty grade 12 bolts? ARP head studs were too expensive but if i build a proper motor ill sure get em. I just figure that torque and tightening procedures for Non TTY bolts would be somewhat diff then for stretch bolts. Im also waitin on a response from Morona Racing bout torque specs for his grade 12 bolts.

Bolt torque/stretch specs allways come from the faster manufacturer.

@Devan

For the fastest answer, call Morona.

I'd imagine as the years go by, and popularity of modding V-6's decreases, Morona checks his e-mail very infrequently.

For instance, his webpage has been pretty static.

HTH & YMMV

He means fastener. You’re probably looking at a two step procedure with the second being in the neighborhood of 70ft lbs.
