I have pointers on some of the problem areas that I corrected. It is far from done but close in the pics here. Not much unshrouding possible at the bowl edge due to the small 88mm cylinder but corrected just the same. This will drop compression a bit but that can be gained back by setting the squish (moving piston closer to head).

What did you use to clean the surface area?

What did you use to clean the surface area?

After the step you see in this pic...you're going to laugh...the same 400, 600, and 2000 grit we used on your tank...I mean the same old used up paper! [laugh]

PS: The action you see here is a dangerous game. You should have a valve installed to protect the seat or make yourself a custom plug.

I was thinking you used sandpaper! Good looking after the clean up.

I am going to measure the combustion chamber size before and after since it will lower compression by doing what I did. This will be interesting to see if I can get it back with the squish setting. If not, I will deck the head ever so slightly
