That's pretty cool! It looks like you've got some D shaped exhaust ports going on. rotarygod says to have the rounded part of the D on the opening edge and the closing edge should be flat; opposite of your (pictured) ports. He also said the intake ports should have a D in the opposite direction. Seems logical. What are your thoughts on this?
I just completed a set of large exhaust ports on some R5 rotor housings (with a bit less missing chrome than yours hehe) and followed rg's advice. First I enlarged the ports to T2 spec, then I raised the closing edge a few mm higher. It's flat across the closing edge with a slight roundness on the opening edge; downward only a couple mm in the middle and blended smoothly with the stock opening at the corners for a smooth D shape. I'm curious what you mean by 'attention' on your opening edge.

Nice work, make a keychain from your new lucky charms.
PS- your not really gonna use a cheap piece of steel exh tubing as your sleeve right? I know your not "that" ghetto.

Really, though, the tubes only serve as an expedient place to attach the intake manifold. The whole point to this port is that the port window size/shape is such that the tube CANNOT go all the way through. The rotor housings will be similar to one of my intake manifolds, most of the actual port walls will be epoxy, the metal is just there to have something solid to attach things to it.

ALright guys play nice.
Pete, Im just more concerned that you will have electrolysis with the steel. alum combo. Dissimilar metal corrosion is not a pretty sight. Alum sleeves cant me that much dinero. Id suggest you spring for them.
