Need help to place value on low mile 3.6 964 P&Cs

[Jim2]

A customer in an unrelated business has a set of 964 pistons and cylinders which were removed from his car and replaced with 3.8 units. The conversion was done when the car was relatively new with less than 5000 miles. The take-off 964 cylinders have seal rings on the surface which mates to the head, leading me to believe they are "late" 964 units. They remain assembled with rings, and wrist pins etc.

On a similar note the same person has a set of Andial race cams which were installed at the same time as the 3.8 P&Cs, but then removed shortly afterwords due to street-ability driving issues. The cam lobes appear good or new but the bearing journals are somewhat scored.

Can anybody provide some insight to the value these would have for resale?

TIA for any advice!

PS. I'll probably end up advertising the p&c for the seller, in the event anyone is interested.
