Awesome. I've been looking to do something like that to my own pan. Just gotta pull it.

Getting ready to replace the valve guides& seals, then will need to figure out the head gasket. I have heard you can rebuild/reuse the compression lowering head gaskets. Has anyone done this? It seems you could take a standard MLS head gasket disassemble and reassemble around the compression lowering one?Image

I think you should run standard compression. With a good ignition tune, you should be safe, and the powerband will be better all around.
current:
-mk4 tdi wagon with some mods
-TDI b3 90q, holset turbo, be strong little connecting rods!
-the turbo tractor
past:
-11 second 90q junker
-20vt swapped 90q winter beater
-efi 10vt 4kq
-way too many other long gone urs's, 200's 4000's, b5's

Problem is, I can't afford to have it re-tuned. I had a old crank case tube and modified to keep oil from getting to valve cover. With stainless steelImageImage

Still have the original, but this one should work.

Many people here could help with an basic ignition tune that won't detonate. Even if you take a few degrees out of the whole map that would help. You can always repurpose a knock sensor to hook up to a set of headphones with a little amp or directly into the cars head unit via AUX in. Then you can listen yourself. I did this in my 4k. Was so handy to be able to plug it into a laptop and record it during a WOT run.
