t will be good. off by 0.003 is nothing. preload at .035 vs .038? no big deal

They're getting a misfire on #4 exhaus, primary running much cooler than the others. They're saying it's because that push rod is too long and causing the valve to not close. My notes indicate I measured 7.511" at zero lash, and I ordered a 7.55" because of Al saying the tolerance was +/- .005". The Manton push rod we installed in that guide I measured as 7.556", and it's stamped as 7.561". I asked the shop when I can come up to re-measure, and I've asked them to confirm there isn't a vacuum leak on that new valve after the valve job before I reorder. My understanding is they had the machine shop handle the valve job, and my shop supplied the OEM exhaust valves.

The pushrod length is likely fine. You actually LOSE preload as the engine warms up. Even if you are 045 cold, it is still 035 warm. It is fine.
Valve should have been lapped in. Simple compression test will verify the valve is not staying open.

I'm open to recommendations. There was a bit of grumpiness between me and one of their employees last week due to delays, and now I'm not supposed to be there unless the owner is there. I'm waiting for the owner to approve me to come up after work tonight to re-measure. If I remeasure and it's the same or insignificantly different, do I still re-order? I might be able to get the replacement pushrod tomorrow if I order from Manton soon enough today though, which would need to be before I'm allowed back at the shop.But ordering again without re-measuring is another guess...?

For the first month, basically all of my communication had been routing through the tech that I've known for maybe a decade, between multiple shops. He has good intentions, but he often tends to tell customers what they want to hear, which doesn't always align with business practices. The owner wasn't aware of my concerns until I had an argument with the tech last week.
I had a long discussion with the two shop owners last night, and I promised them to keep the details private. However, they promised accommodations and review of internal communications.

I did the saccity barbell and remember being happy with it. it was too long ago, but I do seem to remember oil pressure at idle increasing some. not like it jumped from 25 to 40, but maybe form 20 to 25. I also installed that bypass blocker in the oil filter mount.
