The old saying that comes to mind is why is there never enough time to do it right the first time, but always enough time to do it over...
Well if you do buy another set, my advice is open the top ring gaps WAY up. I'd say like .020 or slightly higher. far better to be a little loose than have those ring gaps close up under boost. It seems that the ring lands always break on these pistons.
If you end up buying a set of forged pistons from our vendors, as you probably know you need to run these with about .004" clearance. The only problem in doing so is that the way they're sized, running .004" clearance puts the set of rings they supply you with with WAY too large of ring gaps! Like .026-.030" It's like the piston manufacturers or vendors are sizing these pistons with cast piston clearances! It's like they're made about .002 too large. I try to get around this by either ordering custom pistons or if buying from a vendor, to buy the upgraded ring package which will be a file fit .005" over ring size. Venolia pistons were famous for it. Wiseco's are made maybe .001 smaller. Still too large IMO. Remember π, each .001" increase in bore will open the ring gap up by .00314".
We all feel your pain. Sort of like shocks for our cars, there is garbage econo shocks/struts and then there is gold plated over hyped and over priced Koni's and it seems like nothing else in between.
