Yes that is good thought IMHO. Well, what we don't know is how much oil is lost through an extra .0005-.001"... or .002" or .003" and on up to how much wear everyone's blocks really have. I suspect some of the sharp machinists here are are checking this parameter... I'd love to hear their measurement experiences and their take on this.
It would be nice to have an easy method of checking this... like Plastigage for lifter bores! Maybe a set of 3-4 precisely ground mock lifters in stepped sizes? Of course then a solution would be need for worn bores. Uh-oh....
