That was done a long time ago and it was made of Alum. There was a Templet in one hot rod mag. that was true to size. I made a few back in the mid 80s before I started making the bolt-in tear drop style lump.
Anyway the fit has to be tight to the port so you can get the right torque on the head bolt. And you need to make sure that the treads have sealer on then Or you will end up with water in the intake port, as the head bolt is in the water jacket.
I hope this helps.
PS. it also had a small tab like at the back of the port and a small indent was made in the back of the port to help keep the wing in place.
God doesn't like ugly.
