I'm slogging through head replacement and have tried a technique that, while I can't say it's worked out well because I haven't run the car, seems worthy of mention for others contemplating the same procedure. I had the heads cleaned, then dremeled out the corrosion to leave bright, shiny pits and filled them with JB weld. Cured overnight. Then I spray-glued 100 grit sandpaper to 3/4 inch smooth plywood, mounted the sanding surface on a table, and sanded the head in a circular motion until all was perfectly--and I do mean perfectly--flat. I have pictures of procedure and results if anyone is interested. Everyone may do this, I don't know. But it saved me a couple of trips to the machine shop and went really quickly. I tried it wet and dry, both have advantages/disadvantages. I'd just do dry next time. Jim |
