Hello everyone, I've got another question. First off, does the '58 Plymouth poly 318 need to have hardened valve seats installed to run on unleaded gas? And if so, do they need to be machined into the heads? If someone's had this done, can you give me a ballpark estimate of how much it cost you? I'm trying to get a general idea of how much this is going to cost and how long it will take. Thanks for any help anyone can provide. Arthur Ash
