Here are a couple more of the engine. Externally there is a lot of rust but internally it looks good. There's little wear on the cylinder walls and the valves look good.
I also disassembled the heads today to do some mild porting on them. I finished one and started the other. I'll finish it up tomorrow and post some better pictures.
This is a stock exhaust.
I concentrated on the roof and pocket and didn't make the port much bigger. To my surprise the short side radius on both the exhaust and the intake didn't need to be touched.
Intake after blending.
Intake after shaping the valve guide. This is all that was done to the intake.
