Super Jet Putting a 61x exh manifold on a 6m6

Looks like the bolts don't quite line up. Hog out the manifold holes? Any other trix?

Don't know what you got there! The screw holes line up, however the exhaust openings do not. You can open up a 6m6 for 61x cyl. duty but not the other way around.

I think I'm going to drill and tap for the larger bolts. Think it's 10mm compared to 8 on the 6m6
