Mazdaspeed bridgeport for 12A

NOS R5 front plate, bridgeported by Mazdaspeed in Japan for Tom Walkinshaw. This is a spare plate, identical to the ones used in the 1981 Spa RX7.

Should be great for a template 8-)

That's a good product base you're developing there ... LSD's and bridgeports. Feel free to use my TWR as a test mule ;)

Any reasoning for it being bad porting at all? :?

Looks very similar in shape of the Racing Beat template i used. The benefit in having a plate to use as an example is being able to see the inlet angles used, the template doesn't give you that - only an outline to scribe on the plate. Just my two cents.
