Who failed ls7's?
I run new LS7's in my ls7. If they survive my engine they will comfortably survive yours. Morels are good, but i dont think you will notice a difference unless you have very high lift/aggressive ramp cam and go with larger lifter wheels. Your money would be better spent on fresh rockers if yours are high mile. Avoid the comp trunion kit. Other money well spent is high quality (PSI1511)valve springs and retainers(ti) as i said earlier. I dont think your redline is 6600... If you want to turn that high you need lighter valvetrain that i mentioned, as referenced in my superchevy article.
