Piston hitting heads!

[vincent]

When putting Edelbrock heads on one of my french motors, I found that the pistons just touch slightly at their peak point. I made a cutter to the shape of the piston and deepened the pockets in the heads. When doing this I found that those 4 pockets were not exactly parallel to the head and of slightly varying depth...
Here is a pic of my cutter. It is just a shaped HSS in the slot so I could make different cutters for other shapes, if needed.
