731 Head Intake Port Picture

[FileCabinetRacing]

Does anyone have a picture or diagram of the 731 intake port with something to scale? Trying to start work on an adapter but I cannot remove the manifold at the moment as I am stuck dailying my e30 race car.

Thanks

i did some time ago (traced a silicone port mould onto grid paper) but may have lost it. I will check if i still have the grid paper and/or the port mould
