Stage 1 or STage 2 heads?

I dont want to get a new rear end anytime soon, and plan to get a 230/236 cam with some LT's. The Stage 1's are 1.94” intake/1.56” exhaust, and the stage 2 are 2.00” intake/1.56” exhaust. These are from Combination Motorsports. I dont know if I want to spend that much more or if its even worth it. Any suggestions?

Llyod told me that the larger valves would flow about 10 or so more cfm at .600 lift and maybe 10-15hp depending on the other mods. 5 here 10 there. It adds up fast. Worth the extra cash to me.
