Found my problem... Here you go...
"That is the front cam bearing thats obstructing the lifter bore, rubbing the cam lobe, and was holding the lifter off of the base circle. Guess we can chalk this up to Moe's bad luck instead of his bad driving. Anyway, out she comes again..." quote Bluecat on kyhorsepower.com
So basicly my front cam bearing took a walk on me and screwed some stuff up. 1600 miles on this motor before that happened. Good news was i turned the motor 7200 rpms, hit the rev limiter a couple times and not one of my pistons has a mark on them and none of my valves have been touched. time to up the rev limiter when it gets back a little.

LS1 cam bearings are just like SBC cam bearings they are an interference fit. Some builders put a dab of sealant or loctite on the back of them to ensure that the bearing doesn't move under load. This is more an issue with aluminum blocks than iron blocks from what I have seen here.
Yes you can replace the front bearing easily, but what about the rest of them. There may be another bearing that is ready to walk as well. Better to be safe than sorry.
