Head bolt torque:
55 foot-pounds, have a coffee break
65 foot-pounds, have a meal break or wait overnight
75 foot-pounds
Not sure on the exhaust but guess at 15-20. Retorque after running in.
Head bolts are 7/16" UNC from memory but not sure on length. Have you got good oil access from the block to the head (Simon dealt with this issue well)? I lightly grease all my bolts with moly grease.
