94 4.0 head bolt question
i have a 94 4.0 apart and looking at replacing the head bolts, or re-using the originals.
first question > has anyone replaced these with new hardened(not TTY) bolts instead of the torque-to-yield new bolts?
second question> if re-using the originals, I know most guys are going to say this is a no-no but i wonder if torquing to say 65 ft/lbs would work.

1) It looks like new torque to yield head bolts are $40-50 so how much are the other bolts?
2) Absolutely not. Wouldn’t you also be compressing the head gasket more by over tightening the head bolt? Why take that chance?
