Pulled pistons to replace and Found Blow-by culprit

[GSTurbo1]

Ok so I'm replacing my piston's with je's new Asymmetrical pistons, I took the pistons out today and found the culprit to my blow-by. And most likely my low compression numbers, 150 psi give or take 10 across the board.

The walls are not scared, slight slight ridges barely feelable with the fingernail. A good flex hone to the wall and we should be rockin

Before running the engine after it is back in you need to get a better tune on that thing. It is pretty obvious that you are running too much timing, or just running it too lean.

The cylinders may not be scored but I'd bet good money that they aren't round either. Especially after that much heat and abuse. I'd recommend having a machine shop take a look at it and at least mic the cylinders so you know where you stand.
