NEW INFO

I took the heads off my motor, and there you have it the upper ring of the pistons are breaking off! I dumped a little oil and did a copression test and the pressure on #4 cylinder jumped from 100 to 180! So I knew before removing the heads what the problem is.

Now for my *****ing, this is the second set of KB Silvolites that I had the upper ring of the piston break! I'm calling the place that built my motor and *****ing. They should have known that the upper rings on them pistons need special filing and gap. So what could cause the pistons to break like that? Would over heating the motor do that? Running it lean??

What cheap pistons would you guys recommend? And I think I'm going to use regular rings, not chromoly this time.

Here's my question the valves can't be bent or messed up if the pressure climbed like that can they? So I think maybe a lap job and use them. Maybe get a vacum test too.
