One auto wrecker has a 210mm gasser but they are asking $175 and it's about 100km away from me. New for $100 sounds better! :3
Woot!

Call Giles about the flywheel, I think he has a few. If not, try
Hasan on vwvortex, he should have some.
On porting the exhaust ports, some people say to leave a step on them where it meets the manifold. You may want to do some reading on that.
You may want to consider putting a few layers of duct tape on the valve seat just in case something slips when you are porting.

Much thanks!
I'm going to run the AUG I have for now sadly until I can build a transmission with a longer gear ratio. I'm guessing the trans in my car was a swap or just another weird franken that came from wolfsburg.
It's getting tired and I dislike how high the rpm's are at around 90km/h. Plus the speedo is out by 10~km/h so for a few weeks I was really pissing people off by accident. I was thinking the same to everyone riding me xD.
What code are you guys running for a swap?

Sorry I looked around and could not find anything about stepping the exhaust port. I can picture it but reading the theory for it would be nice. I was going to leave the exhaust ports about 2mm smaller than the exhaust gasket. At about 3/16 deep I will start to taper.
So basically right now I'm going as deep as I can on my 91 head until I feel it's open enough or hit a water jacket and learn not to go that far.
I'll admit I'm puter illiterate like Ricky from Trailer Park Boys and even going over the Porting FAQ confused me a bit. The diagrams, writing and my brain don't work that way sometimes and I have to watch multiple videos and pictures of how to cut in the bowls and ports to understand the do's and dont's.
I'm sure some of you know the Red Green show saying

i wouldn't worry about the step, i'd think that just adds turbulence, and i think the idea of leaving a step is to help keep the gasses from reversing back into the engine, but diesels hardly have any valve over lap, so by the time the piston is going back down for the intake stroke the exhaust valve is closed.

Use common sense and DO NOT remove any aluminum material directly behind the anchoring area of the valve seat. You do not want to do anything which will encourage/cause a "dislodge" of that seat. The one photo has be a bit concerned....to be honest.

right, i made mine even with the valve seat, but you also need to keep the port offset from the set, it is intentionally offset to encourage even flow around the valve.

I'll just open the ports by the gasket and leave everything else alone near the stem/bowl.

it's ok to open it up around the stem and bowl, and take the harshness out of the radius of the turn, especially in the exhaust ports, u just don't want to go hogging everything out though.

Ok thanks. I got scared I wrecked a good head. I haven't cut anything extra from around the seats just 220 grit right up to it. Thanks all and I'll keep truckin.
