Depends on the car. Doc has done a pretty spiffy job of in car cam swaps on the older model A-bodies (see the article "In Car Cam Swap" by Doc in the articles section of this site). In most cases, you will need to unbolt the motor mounts, raise the engine so that the "X" on the timing cover clears the lower rad support/bumper, then remove radiator and grille. It may be possible then to do so... again, this is subject to the car you have. I am not 100% sure on your car, but I am sure someone else here can tell you straight up whether its really "possible".
Far as the head goes, if the engine runs well, you CAN leave as is, and just run it till they don't quite seal right anymore. At that point, you can yank it, and run a newer head, or have hardened seats installed (also a good time for O/S valves and porting...
). If it helps you sleep better though, you can just get a later head, and slap it on there... you just never know what the shape of the head is in, unless you take it apart, and if you do that, you may as well just have the machine work done, and be done with it.Good luck!
