Dear Paul
    While everyone is talking about exhaust flanges 2bolt/ 4bolt I got an idea. 
Why not  mach up a flange with 6 bolt holes,2bolts to be bolted on to the oem 
pattern and 4 bolts for the new pattern these drilled holes in the flange would 
be used as a  drill jig  to spot drill  and drill the block ready for tapping 
the new 4 bolt pattern. Then after drilling the 4 bolt pattern if you wanted 
to cut off the top and bottom bolts you could. That would leave  you with a 
perfectly aligned 4 bolt pattern.

Sounds like a good plan but a lot of people don't own big band saws.
