They look good, but your intermediate port is small. I guess it doesn't matter though, with a P port.



I've got a set of R5 end plates and I think an N intermediate plate. All the ports are average height. Not as tall as '74-'75, but not as short as yours. Also, the outside of the intermediate plate has tall runners, like the US spec FB ('84-'85 for sure).

You're right. The manifold for the PP motor is custom made to block off those four ports.

I posted a photo in the thread dealing with Peripheral Ports by Heath. Here's another of the new engine being assembled.



What opinions are there re: the placement of the two shims between the water pump housing and the water pump? The FM says to place two shims at points 2 and 4 but my original engine didn't have them, and water leaks weren't a problem.

One shim on each stud. They're good to use, but I've also seen an engine not leak without them. I got a set of new ones from Banzai for my 20B.

The shims are to account for the gasket thickness at all the other mounting points. Not using the shims will cause the waterpump and housing to distort a small amount when you tighten everything up. You have a killer motor, why skimp on two shims?
