In my opinion, I like Comp cams 12-242-2 kit for flat hydraulic lifters. Good all around cam. You might be limited by your heads though. Just find some second hand Alum heads off CL (L98/ZZ4) for cheap, then you can bump up the compression ratio with different pistons for even more umph, add ratio rockers while you're in there and add a better intake with a nice new carb, oh and headers..........what were we talkin about?
Every time I change one item it starts the snow ball rollin' and before you know it i've spent 1000 clams! But it's the cheapest therapy I know!
Go for it!
