I understand some people lose pinch after a couple of gallons, sometimes it happens that way you just have a looser fit which to me in my experience does not last as long as engines that have a tighter fit
Why would you want pinch after a couple of gallons? You should feel mostly compression at this point. If you still feel a lot of pinch TDC, that's just a sign that the motor isn't completely broken in. That's nothing to brag about.
I prefer engines that can take a pretty good race tune after a few quarts. The b5 is one of those. They don't have extreme pinch brand new, but seem to hold their compression better than many brands. No need to bench race for a couple of gallons.
