Working like mad to get the car back running, today, I put the new heads on the newly painted (red) shortblock. The Chilton manual I have details a 6 step procedure for installing the damn head bolts:
1. Torque to 28-31 lb/ft
2. Tighten an additional 90 degrees
3. Back off bolt one turn
4. Torque to 28-31 lb/ft
5. Tighten an additional 90 degrees ( I'm wondering what the torque value is about now)
6. Tighten an additional 90 degress ( I know I'm gritting my teeth as I'm expecting the bolt to break off in the damn block)
I followed this procedure, but the additional 90 degrees required a big-assed 1/2" breaker to get the bolt the final 1/4 turn. And the drivers side head was a "push" rather than a pull, (bout wore me out) Seems like I'm torquing 460 head bolts. Chalk me up as mildly concerned
