I just got a set of bare 243's.. I was wondering if it would be worth putting the manley pro flo valves in them or just swapping the stock valves out of my current 241's. I could just put them on with some new head gaskets.

I am ready to put a f 14 cam in now. but would rather put the heads on at the same time. But with the stock valves or manleys, but thats gonna be extra $$$... valves 240$, gaskets, lifters and so on..
