Head Bolt foot pounds

[Jcornaglia]

I'm replacing blown head gaskets and my Haynes Manual say to torque the bolts to 37 ft lbs then 90degrees. The felpro bolts come with instructions that state to torque the bolts to 44 ft lbs then 95 degrees. Which is the correct torque? I'm tending to lean towards the felpro bolt of 44 ft lbs? Any help would be greatly appreciated - 1998 pontiac montana

For others reading this, I found information that GM did change the head bolt spec to 44ft lbs. and 95 degrees so ignore the Haynes manual that states 37 ft lbs. Check this against your MODEL YEAR. See the link below. Hope this helps
