small block cams

I think the website says 2000 on the stall, whats a good brand to go for.
what all can I get a 8 1/4 out of that'll fit with minor or no mods and if I can get that sure grip carrier for free or next to nothing would it worth purchasing a gear for the 7.25 and if so where's the best place for that and will any 7.25 gear work (diff years/diff models?) I kinda figured the closed chambered heads would be the best plan but if I pull the engine apart to overhaul it i'd be re-ringing it and possibly replacing pistons if it needed bored so that's why I considered the "taller" pistons.
