If the original valves are not bad, should I just have them ground or should I replace them? If I do replace the valves I will be using Elgin Industries steel replacement valves. Will it make a difference because I'm having hardened exhaust seats installed? And just what is "bowl blending"??? Well if you break the head off a 40 year old exhaust valve that has been heat cycled a 100,000 times and is weakened, stressed and plum worn out you will see what a few dollars saved you!!!! I have and it ain't pretty. Course I got to build a brand new motor heads and all! Solid advice, they have been known to get brittle, alot of risk vs. cost

Thats why some on this board recommend the areo heads with the plan to have them examined and corrected. Keep old mopars alive.

I purchased all my own parts which has ran about $400 as well for valves, springs, retainers, locks, seals, rockers with shafts, freeze plugs and studs. That does not include all of the engine gaskets. I am resealing the engine. I do not want to go with aftermarket or any other heads as the goal is to keep everything original. So far, no one been able to answer my question about modifying the head for better valve cover gasket sealing?

Yes. The valve covers and everything else is all stock. I will use an inch-pound torque wrench when it comes time to put on the valve covers.

I don't think 71 heads had hardened seats
