As for the lifter, I'm guessing bean counters had something to do with the lifters falling apart, I never seen a 6.1 or 08 back 5.7 do it, something changed in 09+.




I did exactly what you said. Had to grab another new head (drivers side eagle), 6.4 srt cam and springs ,new lifters and took 20 thousandths off. I used all ARP hardware for the hell of it.

Any idea what the compression is after taking 20 off the heads?

I wanted to have the bad head cut apart to see what the heck happened but there was a $150 core charge so I sent it back.

It amazed me how easy this engine was to work on. Almost makes me want to put one in my Challenger.
