I am replacing my head with a nonjet, and I need the correct torque setting for the bolts.  I also would like to know if I should torque the bolts on the cam as well.

Yes I am using ARP head studs,  the gasket I will have to check in the morning.

Thanks In Advance

The two small head bolts are 11-15 lbs.

The larger bolts are 65-72...cold,  73-79...hot

Cam Bearing caps...14-15

Cam sprocket bolts...37-43

The tightening sequence on the head bolts are, with the 11s being the smaller two in front:

11--8-6-1-3-9
11-10-4-2-5-7

Nice JAinsworth!! Just a question! What head gasket are you running? And what bolts? (new stock or ARP)? Some head gaskets are a little different in tourque specs. If you have a MLS gasket it's a little more and the ARP's are a little diff. too! Just asking?

Those are factory specs for a stock engine.  The ARPs are higher and even with them it's different using 30W oil or moly lube.

I think since JAinsworth did such a good job with that post, this should be moved to the FAQ section... 8)

NEVER  NEVER  NEVER USE A  1/2 DRIVE  TOURQE WRENCH TO TOURQE BOLTS UNDER  25 FT LBS ,,AND EVEN AT 25 FT LBS I'D BE LEARY

most 1/2 drive  tourqe wrenches  will not read  acurately  at those low  numbers ,,use a 3/8 or an inch lb  t/wrench

It is more if you use motor oil.

I always use white assembly lube. Heres the specs: Tighten in sequence according to the FSM in a two step process. The sequence is in the FSM page 9-23. ARP Head studs are tighten to 90 foot pounds. So tighten them to 70 in the sequence according to the FSM. Then go back and tighten them to 90 foot pounds still using the same sequence in the FSM.

This is a copy of the sheet that ARP included in the 2074202 head stud box..... ( April 2008)

80 lbs with ARP MOLY ASSEMBLY LUBE.   or 120 lbs with 30 wt oil.
As per the instructions-  DO NOT USE ANY OTHER MOLY LUBE or head gasket failure can result.

I can't find any documents to back up the 90 lb torque with white assembly lube.

Can you back that up with anything  more than just an opinion?
