DO NOT INSTALL HARDENED SEATS. With that said contact Russ Martin in Grass Valley, Ca. CenterVille Auto to get YOUR heads done up properly.

The Nailheads have a better alloy of cast iron that seems to be able to resist the valve seat recession that is common with the cheaper cars, Chevy and Ford etc. Also there is not enough metal in the seat area to support an insert. You risk cutting into the water jacket and then you have a big paper weight. Big block Chevy's are bad about that too. I believe that your desire for money savings will be futile in this endeavor. Get your set done so you know what you have. Buying used heads for anything but core value is a very risky business. If you buy a used set from somewhere across the country and they have a sledgehammer and pliers quality valve job on them. Then you are back to square one. If the guy might take them back you will still be out considerable shipping costs for shipping them twice. Anybody that has a fresh set will want the same amount of $ that it will take to get yours done. If they don't I wouldn't trust them. Good luck.

For the nailheads the newer fuel does not provide the valve lubrication of older fuel. I add Marvel Mystery Oil to the fuel to aid in valve lube. I've been using Marvel Mystery oil in mine (fuel and crankcase) for 41 years

About every 800 miles I run a 50/50 mix of LL AV Gas and pump premium gasoline in my Buicks with nailheads. It gives you the lead and the octane that they need.
I have been doing this for the last 25 years with great results.

How much Marvel Mystery Oil per gallon of gas do you use?
Thanks in advance.
