i'm going to port my stock heads soon but i would like to know the best aftermarket heads to buy. i would really want more of a head/cam package so i could get full use out of the new heads. i do have a 305 and my mods are in my sig.
thanks for all the help guys

anyone?

 

The L-98 Corvette alum heads will bolt on the 305 and give you a decient increase in air flow while maintaining the stock compression ratio. The L-98 heads have 58cc comnustion chambers.

I like those too - but I've heard of people porting the stock ones to flow just the same - even better
