zolo, If you cut the inner surface, you will be rasing the compression. I would think this is not a good idea, unless you are going to use high octane fuel. I have belt sanded the surface on the heads to take out pitting, and have not had any leaks. If this path is very deep have it welded.

I need to cut a head face where the steam cut a path and would like to know what the proper size should be to recut the inner surface where the metal ring gasket goes. I am sure it is an important size. >Zoltan > > > > |
