now lets say i buy a set of (8) ferrea stock sized valves. would i HAVE to upgade the exhaust side? would i have to upgrade anything else as these are the STOCK sized valves...cuz right now i just need the intake side of it.

you can change intake valves only if you like. i would replace valve guides and valve seals while you're at it.
