Hello Again,

All in ft lbs. unless noted.

flywheel housing: 118-148

connecting rod nut: 118-137

camshaft bearing cap bolt: 93-108

cylinder head bolt prior to 2002: 184-210

use the date on the rocker cover

rocker cover (2 & 3 piece) 22-28

Cylinder head bolts must be coated on the threads and bolt to head contact area with international compound #2, more commonly called peanut butter from the Detroit dealer.

The rest are standard on the chart from this link, be sure to coat all threads and head with oil except the head bolts as stated above.
