the two types of keith black pistons that i want for my 351w seem identical except one type of piston has 5/64 in. top/second ring, 3/16 in. oil control ring (KB 151), and the other has 1/16 in. top/second ring, 3/16 in. oil control ring.

what is the difference between the two types of pistons?

The 1/16", 1/16", 3/16" is a very common Ring set. Most SBCs use this set.....
There are much more ring variations available in this size.

5/64 is THE most common ring size. It is the OEM spec for long life and sealing..
1/16 is the thinner race spec ring.

Any downside to the 1/16 (standard tension)?
