351W heads will work, just use the ARP bolt kit for it. Mill about .015" off it and port out the exhaust side only. The 351W has the same ports as the 289/302s. You have to use the C9 castings. Actually for the cost of the heads + machine work you might want to look at Aftermarket cast iron heads. All depends on what you already have and how much you want to spend. Or you could do the old 289/302 trick and put the larger Chevy valves in it and port it out. That also works well. The exhaust port is the biggest handicap.
