Everything I've found says that is for the 86mm bore, '75 and up.

 

I'm going to stay with Felpro 21157.

The FelPro head gasket should not require re-torquing I have understood. I was going to go FelPro as well until I talked to Dave Rebello who suggested the 11044-N4221.

I'm sorry.  You've already told that.
