SS/GT SBC engine combo?

I would go with the 71 487 head combo if you have to run a 350. GT Hp is 290.

If you want to get away from the older heads use the 1980 350 190 hp - 298 NHRA with the 450 and 624 heads. The port spec for the 450 head is pretty nice.. 450 = 168 60

the 487/290hp head was good looking........if you still can find them. has anyone had sucess with the WORLD PRODUCTS 300hp replacement units? i think there's a weight penilty but i wonder if the performance/aviability aspects are advantagous?
