piston ring alternatives

[recian]

So I've been chatting it up with LSR about pistons and rings for my truck. Great advice and I'd love to put some higher comp pistons but cash is the big issue. Since the head has to come off I'm gona redo the bottom end and finish the whole engine. I'm stuck between a rock and a hard place. There's one staple in my build now and that's piston rings. LSR recommends some good rings but theyre specific to that brand piston and would require replacing pistons which is alot of extra cash. Mitsu has discontinued them and I've never had luck with ebay china rings. They never seat right. I found these and was wondering if anyone's used them before. If not can anyone offer a OEM alternative?

However I've read in some places that the 3mm ones listed there are .040 over rings also. I dont plan to bore and put oversize pistons.
