Gen 5 Camaro Internal Engine Tech - can i do a cam change without pulling the heads?

i have a 6.0 an i dont wana pull the heads just to put a cam in it

no need to pull heads unless you need to change the lifters

just use air nozzle in the spark plug holes to hold the valves up if your changing the springs and no head removal needed like jay lt4 said

Not being rude but If you dont know that Id prob pay someone else to do it for you.. Just my 2 cents.

Pen magnets FTW! I believe Scoggin Dickey also sells a lifter support tool for LS engines.
