I haven't abandoned the thread, I just haven't been able to find anyone with 5/16 - 7.400 chromoly pushrods in stock, been on back-order since May. If anyone has a source for them in stock I'd appreciate the info!

compression test
Although the numbers, 150 and 153 are really close to each other they are low if the engine is stock. Compression should be 180-200 when the engine is hot and WOT. Was the engine cold and/or at WOT when you did the test ? Long shot since the miles are low but maybe timing chain jumped since that would cause low but even compression.
If those are your numbers, then you may have an exhaust restriction. If the engine is not running smoothly, there should be misfires reported. A lot of techs forget to look for individual cylinder misfires if a p0300 code does not show up. Could be as simple as a crank sensor relearn to solve your problems

Agree, seems like Valve Spring(s)., been there too. I favor CHE Racing Trunnion kits.
When you or whom ever did the compression test, Did they remove all the plugs at once and Hold the Throttle Body Wide Open ?
If the problem isn't, springs, rockers, or push rods, then perhaps time to pull the Exhaust, from Cats Back.
Have you tried disconnecting the battery, then reconnect and make a few test drive, from a Cold Engine ???.

Just came from another respected shop in my area where I asked him to pull the covers to be sure. Long story short, thorough diagnostics, he found no reason to look at the valve train and doesn't think it's the timing chain either, recommends top end cleaning and fuel system additive.
I guess I'll try that and if it does nothing ask him if he wants to pull the covers off just to appease me.
All 3 shops find no codes, no noises, no smoking exhaust, say everything is within parameters and running OK, no need to look for an internal issue.
