this is for the serious engine builders maybe you can help me out. whats the most you can safely mill a cylinder head on a f22a. ill be using a new stock head gasket. and want to run on 92octane without problems. thanks. its going to get done so please dont say im wasting my time and blah blah. thanks fellas. :blink:
i wouldn't mill it ANY more that .030" or else you will run into some piston hitting valve issues... but that's just me
whatever machine shop you take it to should be able to tell you what you can safley mill it.
