So whose used em and who hates/loves em...?

I put a set in my 360 because I heard they helped with your hp/tq, oil loss and such things that follow. Well I was also told it takes a little bit for them to seal to the cylinder walls. So I bought that expensive little can of quickseat dry film powder, again because I was told that helps as well. Well they engine is smoking and its struggling to hold 100lbs of comp in each cylinder, where this engine should be making a metric fuck ton more than that. The heads internals are brand new, and no the rings weren't installed upside down.

Any advice, other than to get gapped rings... I really dont wanna do away with them because they were $300 rings. Any tips for a young buck?
