I figured Id post up some of the recent work Ive been doing.
About a month ago I started constructing a valve spring compressor out of salvaged pipe, which I welded with an old arc welder I have access too. Overall, its not a bad tool, but can use some improvement. Anyway, the goal was to get all the head components out so I could port and polish the intake and exhaust sides, and polish up the combustion chamber.
I used Jafromobile's youtube video - 204 (or maybe 206) Porting and Polishing the Cylinder Head. I think it turned out pretty well. There are a few spots where I should have spend a hairs more time with the 80grit, but overall, it was a huge huge improvement over what was there.
If anyone has any questions, let me know, but Jafro does a pretty good job covering all the main points.
When I get my hands on the intake gasket, I will be enlarging the area a bit, and going over the outside of the runner slightly, but that area is much easier to work with compared to the valve side. I would recommend doing this before going through the hassle of porting and polishing.
Overall time spent grinding (and listening to the damn air compressor) was about 8-9 hrs. I expect the exhaust side to take about 12, and the combustion chamber to take about 6 or 7.
