The Ford Barn - View Single Post - Flathead Alum Heads-Block Alignment

I've been pondering this since gosfast posted about pinning. I was measuring some head gaskets and discovered that the 2 upper/outermost holes were smaller than the rest and fit the studs very closely, presumably to locate the gasket better than if they were the same as the rest. I'm thinking of making short sleeves for the bottom of those 2 holes and boring a short counterbore in the heads to accept those 2 sleeves/rings. That would allow me to make them .050 or so thick, maybe .300 tall, and would act like pins without needing to modify a block to use them.
