Confused on head bolt torque.
 

I have some Canfield aluminum heads.

The ARP head bolts say 60ft lbs

The Felpro T1011-1 head gasket says 70ft lbs and then re-torque to 80ft lbs.

What do I do? I was thinking just torque them all down to 70ft lbs and move on.:confused:

Don't go by what a gasket says for head torque specs. The torque is dependent on the bolts and head material. I believe the ARP fasteners come with a piece of paper that tells you the torque settings to use with different head materials and block materials, but I may be wrong. Anyway, if you want to be sure the gaskets are compressed correctly, I don't think the ARP fasteners are going to fail with 10 extra ft. lbs. But, be sure to use thread sealer.

Cool,

Appreciate it,

My TFS TW heads manual says the following:

_____________________

7/16" Head Bolts: Torque to 35 ft.-lbs., 50 ft.-lbs., and 70 ft.-lbs., then tighten only the long bolts an additional 10 ft.-lbs.

Retorquing shouldn't be necessary after initial break-in, but can be done if desired.

Since they're both aluminum heads, I would imagine it would be the same for either Canfield's or TW's.

Hope this helps,

Thanks, I am all over it I hope to hear it purr tomorrow.
