Would I get the same indications from a collapsed lifter? Even Zero compression in #1 cylinder?

PG-- I'm trying to stay out of the machine shop for the present. This isn't a new build, it's been running good for 12 years, now. [Except for breaking a spring in July of 2014]. All that was done when it was first set up. The replacement springs I got are the same kind as the others. The discussion drifted into the possibility of upgrading to Z/28 springs or the double-coil types spec'd on the mfr's cam card. Those would require machining into the head to use. I will have to check installed height.
I think it's early for a rebuild at 40,000 on a 292. My last one ran for 250,000.
