I have not really check them, but I would say a 1/32 would do.
Maybe you can go into production and sell them. If you have never put them in before. Putting them in dry ice helps or a least in the freezer. Also make sure the cutter is square with the block. also make sure seat hole, and valve guide are all on the same center line.
Maybe you already know how. I just posted this is case you have not done any yet.
