I'm getting the same setup done now on my 87 shee, you really need to get the jugs ported for the 4mill hell with the plate. And yes custom cut domes. I'm getting Kevin at herr jugs to do mine.
Looks real good, I'm thinking of tearing my 03 down this winter and powder coat the frame blue. This is a picture of my 87 project
I need some new foot pegs
Your right I should have done a leak down test when I put it back together. I really didn't know what a leak down test was until the other day. I was hoping to have this fixed by the weekend.
It all started after I had some port work done by herr jugs and my head milled. Should be a good flat surface with the freshly milled head. I have a oem head gasket still in the pack that I'm going to try.
Maybe a bad cap, I can compress it. When you say leak in the system should I see it? I can see what looks like some black carbon it the coolant floating around.
