First of all, if you haven't already, check out the 351c forum. Excellent source of info, far more knowledgeable folks there than I am as regards the Cleveland.
I used Manley valves & Scorpion roller rockers. Ferrea valves might have been a better choice in retrospect (lighter).
I can say that no matter what else you do, using a one-piece valve with a single-groove keeper should be at the top of the list. You don't want the stock 2-piece valve to come apart or slip out of the keeper.

It is a bit out of date (for instance there is a Performer RPM intake for the 351c now, and there are nice aluminum heads from CHI, AFD, and Trick Flow), but it's still a good place to start.
