I'm looking about getting some stage II cams for my 05 SS but I was wondering if you have to pull the engine to get them installed. I've never done any internal engine work before, mostly bolt ons, and want to make sure I'm doing it right.

no you do not, unless you drop your timing chain, If you have never done it before i would take it to a shop or someone that knows what there doing. if you dont put it back on right you WILL mess something up. you cams are right below your valve cover...
