No, you cannot remove the cam w/o pulling both the radiator and likely the grill. The best choice is to pull the engine. What is the "problem" your having with the cam?

As for the lifters I think you can run solids or hydraulics on any flat tappet cam profile. Roller cams are made with steeper ramps and longer durations as a result which would cut into the sides of the lifter bottom.
