well... if you can afford it go for aluminum
if you're on a budget you could get a set of iron 305 HO heads. They have larger valves than a stock head and flow better. A rebuilt set with bigger springs cost me $300 from a local dude. I ran them on a 350 and they made gobs of low end torque but farted out after 4800rpm. They'd go higher in a 305.
The largest valve you can use in a 305 is 1.94/1.50 otherwise you get shrouding.
