Started watching this vid with little hope, seen so many destroying 20v heads on youtube... But this time I was impressed, good port work, AND you left the squish areas in the comb.chamber alone! All the other idiots hack them away, not realizing that that's what creates combustion speed. Nice work!
I'm currently setting into the same job on an AWM head for my Passat wagon. A long time ago (18-ish years) I ported a 16V head for the Scirocco I had at the time, that one was a 1.8L head on a 2.0L Passat block. Comparing the 1.8L & 2.0L heads revealed noticeably larger ports on the 1.8. That work rewarded me with a very noticeable increase in engine response, it would rev up way faster. Certainly some credit would go to the larger exhaust and Euro intake cam, but I'm certain the head work did a lot. There seem to be a lot of parallels to how you've opened yours up to match the valve seats and also tweaked the ends of the valve guides too, with small differences how we both approached that. I did like your solution for using the tubing to spin the valves for the seating process, I was going to be looking for a suction cup type arrangement to put in my drill to spin the valve from the chamber side, but your trick might be what I try instead. My idea would have wobbled a lot if not perfectly centered. Teardown for the 20V head is more of a PITA with the smaller intake ports and getting out the valve stem keepers, I imagine getting them in will be even more 'fun' than their removal was. I originally found your channel while searching for valve stem keeper installation tools & techniques, though being in Canada the significant shipping cost of that tool makes it less appealing. Anyways, nice work & love that shop. I too just smoothed and polished the combustion chamber, removing the minimum material possible. I just wish the exhaust manifolds were as easy to port as the intakes.....
Unless your going for over 800hp that won't make a difference. I'm not saying that from a guess. We made 352whp with an f23. It's making 562whp with a precision 6062 now. Stock cams. Small port head. Next year we will be over 650whp. Small ports.
@@joshpalmer4889 tubular exhaust manifold. 3" turbo back from 42dd, 650cc injectors. S4 maf, IE rifle drilled H beams and wiesco pistons and a bunch of other stuff. The configuration did not last long.
Also what failed on the configuration? I’m setting up Gonzo’s gtt k04 and trying to max it out. So far I have a grams 70mm throttle body, grams small port intake manifold, IE’s street intake camshaft, high flow exhaust manifold (not tubular), drop in rods, next will be meth and e85…
@@joshpalmer4889 we kept blowing charge pipes off and overboosting. We didn't have an issue for a while. But the China tubular manifold was really close to the wastegate actuator and it melted the internals shut. Wastegate was all boost, all the time. With the oem manifold and k04 it was blowing gaskets. The frankenturbo kit was picked up and they no longer stocked the chinafold. The hoses were a joke. Oil feed tube wrapped around the engine bay. Drain back tube was not for awd. Dealing with them made us not want to mess with it anymore. Vagwerks was brought in to fix everything. Pte6062, ffe tubular mani. Snow water meth. 19k in total for the build. If I was to do a budget build, a t3 mani with eBay turbo and custom exhaust. Big injectors, and tune tune tune. Im actually typing this sitting over the built motor on the floor in front of me. Trans is getting updates and motor spun a bearing. Self inflicted.
Could you send me a port and polish service quote to justinderp84@outlook.com Much appreciated!! It’s an AEB I’m going with a Holset HX40 Or Precision turbo

Each video gets better and better! Can’t wait to see this project progress!
Great video btw. I like how you make sure to emphasize how important it is to be slow and take your time
Loving your videos picking up some neat tips! Keep it up bud, hope all is well!😊
Nice video. Informative, good editing, etc. keep em coming Justin! 👍
Hey man so did you only go in with a sand roller or you actually took a burr and cut the whole port before smoothing?
SO the intake has 3 valves per cylinder and the exhaust have 2 valves?
Good shit man!!! 💪🏼

What mods did you have to make 352whp with the f23?

using the big CNC was not an option?
Yeah just throw the head in and the cnc does the job ... doens work that way dude, i guess its way more expensive if u use the cnc
But does a sheer layer even matter if the walls are smooth?
Yes because without a sheer layer there is actually more friction.
I have a 98 Passat I need to do the same head work but what is your price?
I don't really do this for customers anymore, I mainly focus on making products.

Didint see that message at first
That’s ok appreciate you responding quickly I’m gonna keep watching your videos to nail it down properly at my house 👌🏻👍👍
yoo what year is your VW? I have an AWM 01 head.
My car is a 2002 but this head is an ADR from an N/A 1.8 in Europe.
