A couple more pics I came across of some older progress. I am no longer using the AWP timing belt tensioner pictured below since I switched to non-Distributer (using the 9a IM shaft and stuff). Now, I can fit the 9a tensioner with one of my custom 157T Belts.
Before I post some more Porting progress, I just wanted to post this older picture of a finished intake port. Look closely at it compared to the untouched ports and you will see that there is some very poor bowl work and castings from the factory. Even still the AEB flows ~220-240cfm stock. Ported, it has been proven to flow ~ 270cfm.

Exhaust ports are 95% done..
TEMPLATE for Port Matching the Intake.
Yea, I posted some flow number above in the barrage of images last night.
Stock, the AEB flows ~220-240cfm. Ported, it has been proven to flow ~ 270cfm+. Bob Quindazzi (mainly in the 1.8t forums) has some numbers from the heads he ported iirc and they are/were in the 270+ range.
It always helps and it is free hp. The differences that I have made by headwork alone on various engines over the years was my drive . I figured since I am not running a Big Turbo, I might as well make the best of it. I would like to put a set of cams in it, but I am not sure I want to spend that chunk..
I heard that Nate Romero ended up getting 240whp on his all motor 2020 . His ports are completely reworked and monstrous. There are some pics floating around the 1.8t forum iirc. That type of work definitely requires a flow bench and a LOT of trial and error. Obviously, he had very different goals in mind
