305/350 head swap AND a HP question!!!

I had the 1.72/1.5 58cc chambers on my 350, I just put 350 heads on with 1.94/1.5 valves and a 76cc chamber. What sort of things can I expect to notice: power increase/decrease, peak rpm increase? Torque I or D, mileage up or down, and anything else you can think of is much appreciated!!!
