Help needed for '83 head bolt specs

I'm replacing a head gasket on my '83 B2000. After searching for a long time online I am unable to source new head bolts for the job. Mazda online OEM parts catalogs seem to start at '84 (which should be the same engine), but even then don't list the bolts on the fiche. All the aftermarket bolts I have found are for the '85-on engine.

Does anyone know of a source, or have the specs for the earlier series engine bolts so I can substitute?

Thanks guys.

Hey jc50942,

Thanks for taking the time to respond. Unfortunately, the links you have provided are for the FE type engine. The earlier B2000 engine is type F/MA.

If you posted because you know for certain the bolts are the same on both please let me know, otherwise I'm pretty sure they will not work.

i have no idea if they are the same or not.

FYI if you're facing the same issue.

According to someone over in the mazda626.net forum the bolts are not stretch type (only ~60 ft/lbs) and can be reused.
