If advanced yes, but you have to keep in miind that the cam is what controls valve to piston clearance. So, if you are going to run an aftermarket cam, it needs to be advanced or retarded as to the manufacturers specs. Advancing the timing on a stock cam, or on an aftermarket cam for that matter, to much can be dangerous.
Agreed, it can put a major load on your engine if your stock cam is adjusted. Dont forget that if you adjust the valves opening and closing speed and timing...your ignition may have trouble keeping up unless also advanced or retarded to spec.
