"........After two weeks of lying on the floor under the dash on my '56 doing aftermarket A/C I hurt everywhere........"

I hear you Ray, it took me almost a month to recover from putting the Power Steering on the 57 Plymouth last year.

Yeah adjusting the push rods on an engine stand is no fun and doing it in-car is a giant PIA stretching out over the fenders. I'd be interested to know how the adjustable rockers turn out once you get them back. Are you going to need to do something about valve covers for adjuster clearance?
