going from memory here but 1.560 sounds right

I have max clearance .003 from service bulletins

new cam diameter of 1.560 ---from bill stipe site

a low mileage block that I took apart that still has machining marks has .0015 clearance with original cam that shows no wear

a center cam bearing with .005 clearance has the same "open" cross section as the oil feed to the valve chamber ----
