Does anyone know if exhaust manifold nuts are "eliptical offset" locknuts?

Yes I believe they are. Check out my thread, there are pictures.

For what it's worth, the studs and nuts should still be available from Ford, from what I see. Stupidly expensive though.

Stud: N811313-S431 ($1.94 ea.)
Nut: N804178-S309 ($1.50 ea.)

Prices are retail.
 
don't need any, but thanks. I was just looking over the ones that came off and they were alittle tight on the top side. I bought a few new ones from ford and they are not a lock nut. Just a plain old flanged grade 8 nut.
 
I used bolts on some of my passenger side top ones because I was unable to slide my headers over the studs without removing the starter.
