Mike,
If I understand correctly you are replacing a set of rings in your motor which has already seen some use on these bore's. If that is the case was the block originally bored/honed with torque plates. The reason I ask is that the torque plate in simulating the head stud/bolt loading will have given a 'true' bore which will be destroyed if you simply rehone with a rigid type stone hone and no torque plates. If this is so use a 'Flex Hone' ball type of the correct grade to impart the finish you require to the cylinder walls. This will not undo all the good work of the Torque Plates.

My own personal opinion on the gapless ring sets is they make for a drier engine( less low/mid range RPM blow by-leakage) particularly in our Cobra/Gt40 types where most are not used in 'real' anger all the time. In all out racing- Nascar/Drags etc the rebuilds take place long before the wear issue starts to cause a problem & at the RPM being used in racing today ring weight/flutter are the real issue.
