I have a '60 F-100 with a '57 passenger car 312 in it. It has the Ecz-g heads and block. I removed the heads to inspect the condition of the internals, now its time to replace them. What is the torque specs and order for this engine? I assume it would be the same as the 292? Do you have to remove the rocker shaft to torque the end bolts? Thanks, I appreciate any help you can lend. By the way anyone have a 4bbl aluminum intake they want to part with?

 

According to my book on Y-Blocks the torque is as follows:

Tighten all bolts first to 55 lbs.-ft., then to 65 lbs.-ft., and finally to 75 lbs.-ft. You can find a diagram of the tightening rotation of the head bolts on page 75, FORD Y-Block book, author James Eickman, published by MBI Publsihing Company. Hope this helps.

Their are 3 different size head bolts. The 2 mid size bolts go on the end of the heads. That site in the last post read assembly errors.

 

If I am not mistaken, this is a thread where the question was asked in 2000 and answered in 2005.
