marlinjackThe Machinist #5723 AMARGOSA MACHINE 'Running on Empty- Middle of Nowhere'

Thanks Jack! I had read back in the '70's, or was it the 80's, that the valve seat problem did NOT turn out to be the BIG problem the engineers had originaly thought it was going to be. This after they had opened up quite a few New York Taxi cab engines with hundreds of thousands of miles of stop and go, and freeway, traffic on them. I think your right about the machine shops making a good business out of it; because it was from a shop that I purchased my set of closed chambered heads. The machinist had caused me concern as he stated "be sure to have hardened valve seats put on the exhausts, or those heads won't last 5000 miles." So now I think I will save the money and not worry about it, as my 74 cleveland purrs along beautifully with over 46,000 miles on it. Thanks for the info! Regards, Marlin.
