Probably just have the heads reconditioned while they are off. I`m a firm believer in preventive maintainance. Or, buy another set of heads, J,G, Ga etc, have them reconditioned and have the exhaust side milled. Find another set of manifolds, or machinest, or buy a set of new reproduction WZ manifolds.

I am a believer in preventative maintenance as well. Whenever a friend needs a ride, who do they turn to -- me because my cars are always running! I have had a close friend give your same advise. Right now, I don't have the fundage to do that but would love to. I have decided that if this current go does not take, then I will start pulling off stuff. I also has a friend comment that my cam might be outta whack due to the years of her not getting all the hot exhaust out from the leaky/warping manifolds. With the cam off, my timing would never be right and it just leads to another cyclical problem. Validation on that thought process please?
I am searching now for a set of repro manifolds. Any comments as to where to go?
