Hey KZ, I've seen and done both ways over the years. Would not care to even guess how many total, but one thing has always bothered me. That is the blowby evidence clearly showing on the piston skirts and how it increased as piston ring tension decreased. Engineering decreased piston ring tension to have engines last longer than 100k miles, many were not even making it to 60k or 70k.
I doubt the ring tension on these engines is even 5psi, and that simply will not seat the rings (removing the cross hatch pattern) good enough in any reasonable amount of driving.
To test my point of view, on the next few builds you do, before tear down check the crankcase pressure @ idle and 5k rpm- I think you will be surprised when you look at the numbers vs blowby residue on the piston.
