I believe all Fe's used 3/8-16 x 1" or 1-1/4" length for the exhaust manifold I bought new ones for my rebuild and I believe this is what they were.

and the head bolts are 1/2-14 (ford used 2 length's in there head bolts due to the water jacket.

the 2 per side flange bolts or studs were also 3/8-16

These are all USA measurements I do not know if the exported one were different.
