A machist told me this, and I ran it in my 69 Super Bee that I had installed a 64 413 with a magumn cam and never had a problem. Just takes a qt every 3 rd or 4th tank. It acts like a buffer between the valve and seats just like leaded gas. 906 head do not have hardened valve seats.

Anyone know if 906 heads from a 1970 Plymouth Cop car would already have hardened valve seats? Also, I have heard about the seat problems because of unleaded gas. However, I have never yet talked to anyone who has actually had a problem with it. Is this just a rumor, or has anyone on the list actually ever had problems with a Mopar using unleaded? I only drive my 67 R/T occasionally, and I did not have the hardened seats installed in the 915 heads on it when it was rebuilt. 2. Anyone know if the 906 heads would work OK on my stock 361 in my 64 plymouth? It has the original 615? heads now, and I have to take them off to rework. 3.I am thinking of installing a set of the "Hi Perf 440 Magnum" exhaust manifolds instead of the stock ones when I put them back. It looks like it may be a tight fit. Anyone using these manifolds on a 64 B body with power steering and brakes?
