What valve sizes are in ARDUN heads?

Steve recalls 1.8875-inch intake valves and 1.5-inch exhaust valves. He believes the reproduction heads use Chevrolet-spec valves: the 1.5-inch exhaust is the same basic Chevy valve discussed for the Flathead, and he thinks the 1.8875 intake is a big block Chevy intake valve.
