beat to death subject-Delivery Valves

These are out of a P3000 (left). Anyone tried these?

I was going to buy some new DVs, then I remembered I had this pump sitting here and thought what the hell.

Dont look to bad to me, the flutes are taller and run right up to the shoulder simular to a 191 and the collar looks to be in the .040 - .050" range Id quess, seeing the 181 is around .087" or so and 191's are .030". These look to be somewhere in between to me. Lap em in and see what happens. Do they use a 131 or 181 style seat?
