Just finished porting and building up my new motor this weekend - here are a few pics! I used the racing beat porting template for the intake side, and had mazdatrix do the exhaust ports (the $30 bucks i'd save isn't even close to worth the time it takes to grind 'em out 
)
I was going to polish them, but I figured it'd take double the time, and I have my doubts that you get much of a power benefit from polishing, especially with the stock cast intake manifolds.
Let me know what you guys think - First time porting anything... The streak on the intermediate housing happened about 10 seconds before I finished the job (go figure...), but it's no more than 7/10 of a thou deep (.0007), so I'm not worried about it. I went over it with a ground block and 600 grit paper to get any edges off it.
Enjoy...

well I'm not sure what ERW tubing is... but it's from mcmaster carr. 1/8" thick wall, 1.68" ID 304 stainless tubing. Bulletproof, and dirt cheap - cost about 40 bucks for the whole thing. It'll work like a charm.

what was the page or part number for that? I dont see it in M-C. All I find is .065 wall Tubing
45735K215 is the part number
from their homepage, click on pipe and pipe fittings then stainless steel pipe fittings and pipe then elbow --> female 90* elbow, you want the butt-weldxbutt-weld ones, in 304/304l. 1.5" pipe is a bit small for the ports - i'd go with 2" if i did it again.
