My limited mechanical aptitude just got tested to the max by a project that SHOULD be simple. Changing valve cover gaskets on my California 79 Elco with a 350 and air . what a Pain In the A--. I tried 2 different new valve covers, they wouldn't fit under the one A/C bracket. I never saw Chevy S/block v/covers that are sloped on the one side. Or all the crap that had to be removed.
