Anybody tried this? I've got an 03 Z71 with a 6.0 @.30 over and a mild Isky Cam ...We had LS1 heads with LS6 springs until we lost the valves on cylinder #7. I'm looking at the 5.3 heads cause I can get them now and cheap (would love L92's but that aint an option right now). Curious about thoughts on 5.3 heads with this setup.

Thanks..
