I have a 5.7 chevy 1988. I had my engine waterlocked last year and took the heads off to have them magnafluxed and all checked out good but now i was wondering if someone could give me a hand at what the torque values were for the heads and intake and what the sequences were also. Any input is greatly appreciated.
 
"Intake- On all engines, insta

"Intake- On all engines, install the manifold into place so that all the bolt holes
line up, insert the bolts and tighten them to:
30 ft. Ibs. (41 Nm) on 1986-95 engines

Tighten the bolts, a little at a time, in the sequence illustrated, until
the proper tightening torque is achieved.
1986-97 4.3L V6 and 5.OL 5.7L V8 engines
the first step should be 25 ft. Ibs. (34 Nm), the second step should be 45 ft.
Ibs. (61 Nm), while the last step should be to 65 ft. Ibs. (88 Nm)."
