dropping valves?
So the valve gap adjusting screws should all be at relatively the same place, right? And the height of the valve stems those adjusting screws gap to should all be at the same height. right? Mine aren't. The valves on cylinder/pistons two and four seem to be taller compared to the valves on cylinder/pistons one and three. I am concerned. Especially since the same guy who didn't fix my transmission reconditioned my heads, and since the exhaust gap dropped on cylinder/pistons two and four after adjusting them and running the engine only long enough to check the timing, and I didn't like the sound of it.
Sheesh, and I was hoping to get to Maupin next weekend.

Re: dropping valves?
Will that tell me if the valves are stretching, or are the seats are receding.

Re: dropping valves?
Could be the adjusting screws too. If the compression is OK it's probably allright. How much did the gap close? Did you check it cold? You are nervous you know.

Re: dropping valves?
When I initially adjusted the valves, stone cold. After getting the new ignition switch in, backing out of the garage 60 feet to a shady spot so I could see the flash of a timing light, which needed no adjustment, hadn't drifted, and then pulling back into the garage, the exhaust valves especially had tightened a smidge more than I had just adjusted them, after letting things cool off say an hour and a half. No test drive, just idling until the choke had quit on the carb. Everything was cold to the touch, and laying a flat-edge across the top of the valve stems with rockers off, not level.
At this point, looks like I'll be throwing Gretchen's engine in until I have time to figure it out. Our loaner Miata will be reclaimed soon. Have to be at least a one vehicle household.

So Maybe no swap. No ring on the pressure plate of Gretchen's engine, just bare fingers. Is it critical the pressure plate have a ring in the center?

Swap the pressure plates.

Re: dropping valves?
Can't swap the pressure plates. Gretchen's has been balanced to the drive train and the flywheel has a post added that goes through a hole in the pressure plate to align and reference the balance job.

That's never stopped me, drill a hole is the other PP and install. Maupin, you can't miss Maupin and I'll be there for once.

Balance. I do have spare valves in other used heads.

Re: dropping valves?
Neal is this singleport?
If so, I have a shop-inspected good head, although it is disassembled. It is clean and ready to put back together, good valves the werks.
It is yours, maybe trade me for a distributor? Although I think I'm going with the Pertronix SVDA.
Maybe you can make the lakey camp if you get your shit back together. Funny, I gave Randy a 2.0 head and he did the same damned thing last year.
If you are dual port you ar out o luck my fren.

Only one? This issue seems to be cropping up on both sides.

Only one he says.
What are the odds of both heads being bad? I guess it's possible, but not likely they'd fail in the same manner...
