Your L99 heads are just fine, but they will need to come off (replace lifters). Will have to change the springs and related hardware though...assuming you are installing a cam that's worth the trouble spec wise.

This^. And add a new Melling oil pump at the same time. The OEM pumps are known to have problems.

A week ago I would have said slap one in and go if you were an LS3. However, after pulling out my lifters at 21k and seeing them scored from debris...I would strongly recommend pulling heads and at least looking. And while you are there, IMHO, I would spend the $100 for some new ls3/ls7 lifters and ditch AFM. I am putting new ones in. Maybe I could have gotten by, but for as cheap as they are, I don't wanna wipe a new cam/build and have to start over because I cut a corner.
In your shoes, I would be tempted to go with a VVT, non-AFM cam that's a little hotter, and makes it more worth the investment. Don't have to get too crazy if you don't plan on doing a high stall as well. But, I can't think of much that'd be worse than spending the money to have this all installed, just to be left disappointed still because you went with what would work best with those junk AFM lifters.

Thanks for the info, when I start this project I'll be looking into different cams and do the lifters/AFM delete. Don't want to cut any corners either |
