Confused on head bolt torque.

[Dark_5.0]

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.

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,

Dark:

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,
