Thanks Mike, I'm putting this closed chamber piston in an open chamber head so I think the chances of the plug interference are slim. I'm hoping a fire slot isn't necessary because I think the dome height is low enough. Grumps old book says the dome radius should be 1/4 inch, so I guess I have more to do.
