Thanks Rick,

I finally got home and tried threading the Mr. Gasket 5/16" Ford bolts, they go in a few turns, and then stop. I think they are the wrong size. To be honest, the threads show some signs that I am not the first one who was confused by this. I suspect that my engine builder might have run into a similar problem when balancing the assembly. Since 5/16" is a little bigger than 8MM (8.128MM) I think I am onto something. I am going to test the 8MM bolts tomorrow, and if they work, run an 8MM tap through the threads to clean them up and then use plenty of loc-tite.

Nothin's ever easy.....
