Default MVVS Exhaust Port Dimensions?

I've been told that the MVVS 45 and 58 dimensions are close enough that the stuff for a 58 can be adapted easily to fit properly on a 45. ANyone confirm this, please?
Bisson Pitts wraparound for a 58 fit the 45 with a little "tweaking" ??

Engine came in Bob?
Make each bolt hole 1mm oblong towards the centre line, and it will fit. To be absolutely sure not to interfere with the flange weld, use sunken head screws.
Both MTW ( http://www.mtw-daempfer.de/) and Krumscheid (http://www.krumscheid-metallwaren.de/) have exhaust stuff that fits the engine. It is their core business!
Bisson in cowl stuff will ruin the good stuff designed into the engine.
