Exhaust manifold bolt size
'37 Flathead V8. Are all the exhaust manifold bolt holes supposed to be 3/6"-16? The front holes on the one I am working on are messed up. They seem to be 7/16" partway and 3/8" the rest of the way, with the outer part being the 7/16" dimension. No sure what is going on here. I suspect someone has done something jiggy>
