Are you positive you have solid lifters? A friend with a '50 had a '55 engine that he thought had solid lifters. We adjusted them all over the place with little luck. Finally pulled one out and found that it was hydraulic. Used hydraulic adjustment procedure and now "All's quite on the Western Front".
I'm going to get the vacuum gauge out. I'm fairly certain these are solid lifters. When I first started this task, a couple months ago, all the intake valves were at.006 and a hydraulic lifter wouldn't have had any lash at all. I may double check by pulling the cover off the side of the engine.
Thanks for the compliment on the truck. It was a standard color combination from what I understand. Postal blue and black
