Non-ferrus cutting bits and assorted grit flap wheels make short work of porting these. Cross buffs polish them out pretty nice.
It looks pretty grimey, but that's how it looked as it came off the engine upon tear down. I didn't bother painting it or anything since it's hidden for the most part between the heads.
I thought I'd atleast post a few pics of what I did, just to get people thinking outside of the box a little. I thought this may help merge both ports into the tumble port heads a little bit better. Something like this LIM with an SVT UIM might work out even better.
