I have just been drawing some - haven't made any yet but will get around to it at some point. I've made them to the exhaust port shape + 1.5mm to allow for a tube to be swaged out to fit. You're welcome to a copy of a DXF but I would make a cardboard prototype before you get any cut.

Also if anyone has a drawing for a pinto inlet flange that would be much appreciated - b***dy hard thing to draw!
