First suggestion would be to take them to a good machine shop and have them checked out for cracks and seats condition. Hate to spend a lot of money only to find a problem in this area.

What type of fuelie heads do you have, early style , no bolt holes, or late model heads? You didn't make that clear.

Mean-RS,

Are your "fuelie" heads last three numbers on the casting number on the top of the head -461's and do your heads have "stock" 2.02" intake and 1.60" exhaust valves? Or are they 462's or a pair of any of the other heads like them?
The -461's have a flat "squish" area below the sparkplug whereas all others have this area "relieved". I believe that the -461's were the "original" "fuelie" heads way back when since they were the first of the big valve, "double hump" heads in this series of heads. Guy's, correct me if I'm wrong, but didn't -461's come out on 327/350hp, 365hp, and 375hp engines only in 1964 and65?

We do heads like this all the time at work so maybe I can help. As long as the castings aren't cracked and they're the same casting number all is well. Have hard seats installed on the exhaust since these heads were designed for unleaded fuel. Have the heads machined for screw-in studs and guide plates if you're going to run anything more than a stock cam. Regardless of the stock valve size, put in a set of 2.02's and 1.60's, smooth out the bowls, and port match to your intake. Leave the full port work to the pros, but if you do choose to enlarge the ports stay on the roof and don't jack with the short turn radius. Install springs to match your cam and you're there. Have the machine shop CC the heads when the machine work is done, just to make sure you don't end up with too much compression. Kelly
