On the bench the cam is free to lift when the feeler is inserted but on a built engine the chain is pulling the cam down. Just my HO.
I would also add the from a fresh engine I check the tappets at <250 mls then at 500 mls, and only adjust them if they are too close. I then set them all at 1000 mls.

In the late 80's, I've done it like you.
Then, in a few of sleepless nights, I've generated a new solution:
Only once changed in 24 Years. Greetings Urs
I really like your solution!
One (big) question, how did you machine the groove?
I have contemplated the same idea but ensuring the groove is the correct depth over such a large area looks to be a challenge.

I guess a cad drawing and a cnc router would do the job. Next project looming!!!
First I would need to get the cam cover flat.
Any suggestions on that one.
Maybe a new thread?

Another trick I tried was to bin the original washer seals under the securing nuts. I took a 1/2" round of aluminum and chucked it up in the lathe. Bored a 1/4" hole in the center the counter bored with a 3/8" end mill to captivate a Viton O ring prior to parting them off. The counter bore depth was a little over half of the thickness of the O ring. The new seals also have not leaked in 11 years.
The only place I get a notice of oil mist is from the oil cap. The original rubber gasket was replaced, but it still leaked a slight amount. Even tired one from a Datsun. Could not find a slightly thicker piece of rubber to cut a new gasket, as the next thickness was too thick and I couldn't close the cap. Wound up using a thin piece of cardboard between the gasket and the cap. This took a couple of tries, but it has reduced the misting to about a once a year cleanup with a quick spray of brake clean .
