Engine reseal suggestions (possibly cam too)

So I just yanked the motor out of my duster. It had a bad leak on the backside of the engine. Among other minor leaks. I'm going to buy a full gasket kit for it was thinking felpro unless you guy's suggest a different brand. Also I was wondering if I should go ahead and replace the head gasket while I have it out or should I leave it alone? It runs fine.If I pull the head I was thinking I might do a cam swap. I'd like a little more agressive cam something with a little more lope that can run in a mostly stock engine. It's a 225 with 2.5" exhaust. I do have a 4 barrel manifold that will eventually get put on. Any suggestions on profile and has anyone had any problems with the comp cams recently? I know they used to eat up one of the gears.
