Could anyone with a service manual give me the torque specs for:

Cyl Head
Intake
Upper intake

Also if you could find a cylinder head warpage spec that would help Im guessng .003-.007 warpage would be fine

I plan on using copper spray a gasket on both sides of the head gasket anyone ever used the fel pro kit for 3.8 fords if so how did you apply the head gaskets ?

Also if anyone knows of special spots the crack besides the obvious combustion chamber stuff please clue me in on this engine if you have any info

Thanks alot in adavance

Well, according to my Haynes Manual, the specs are as follows:
-Cylinder Head Bolts:
Step 1: 37 lb/ft
Step 2: 45 lb/ft
Step 3: 52 lb/ft
Step 4: 59 lb/ft
Step 5: loosen bolts 2 to 3 turns, then on to step 6
Step 6: 11 to 18 lb/ft
Step 7: rotate 85 to 105 degrees (long bolts)
rotate 65 to 85 degrees (short bolts)

-Intake to Cylinder Head Bolts
Step 1: 7.5 lb/ft
Step 2: 15 lb/ft
Step 3: 24 lb/ft

-Upper to Lower Intake Bolts
Step 1: 8 lb/ft
Step 2: 15 lb/ft
Step 3: 24 lb/ft

-Head Warpage Limit
.007 in

Hope this helps!! You owe me!

thats the proper torque sequence for his car, but just a quick note that 96+ have different length bolts and have a different sequence.
