I remember reading in the past that supposedly Dodge shipped all of their engines with hardened valve seats.
I keep watching the trucks for sale ads and I keep seeing repeatedly people using 440 heads for the hardened seats.
I also keep seeing ads for heads that have had hardened seats installed by a machine shop.
Does anyone know 100% for certain what the real story is????
For example, if I buy a 1969 sweptline am I going to have long-term valve or seat problems running unleaded fuel?
Thanks!
Steve
