Just about every time the subject of refacing rocker arm tips comes up, one of our resident pot-stirrers (No, not me!) starts pontificating about putting an exact radius on them. Of course, he never offers any constructive suggestions on how to do that. In my somewhat biased opinion, anything that is done to correct wear from running these old engines far beyond their projected "use by" date is a good thing. Press on!
