Yes it's possible to do the head and cam swap with the block still in the car. Pleanty of people do it. I personally like working on that type of stuff with the engine on a stand though. Your back will be sore after all that bending over. Keep in mind you will need to drain and remove the radiator to get the cam out and in. One of the bigger headaches is getting the timing cover to oil pan front seal to properly seat with the oil pan still on. You have to drop it down an inch or so. Other things to think about, how many miles on the engine? It's never a bad idea to change the oil pump out if it's getting up there. You mentioned forced induction, what are your goals HP wise? You need to check the cylinder walls with the heads off to make sure they, the rings and pistons are in good shape before throwing boost on them. You mentioned it's your daily driver. This is where Murphys Law kicks in. It's a 22 year old car. Stuff WILL go wrong! Expect bolt heads to shear off, connectors to break, etc... Trust me. Been there and done that numerous times. In theory it's a straight up swap, but be ready to want to set the thing on fire numerous times, tools to fly across the garage, and LOTS of 4 letter words to by used LOL!!!
