Agree with Whimsey. Also try replacing plugs one heat range hotter. Run the car 100 miles and see what you have. Cost maybe $20.00 worth a shot.
How are these Spark plugs looking?

Do the worst looking plugs happen to correspond with the cylinders with the lowest readings?
Those plugs look old to me. They should have nice square edges on the center electrode. So looks like they have been in there a while... Did you re-use the old plugs?

Any idea how can I do it?

He said the car is consuming oil. Hotter plugs are not going to help that.

These plugs are Denso Platinum TT and guess they almost have 30-35K miles on them.
Yes, I guess 1 and 3 cylinder compression and corresponding spark plugs had more burning/stuff on the top of spark plug.
I am going do wet test with a different gauge, not sure if gauge is good? With some oil in #1 cylinder it was showing a value of 270, while for dry test it was 100?

I would also do a leak-down test.
Overkill agree on both your points. The plugs will not solve oil consumption. Do not know if he has put many miles on that head. Plugs are ash and blackened just wanted to see what a fresh plug would look like. Also agree a cylinder leak test is so muck more accurate. It will show where the problem is. To the op I did auto repair for 35 years and also had a machine shop where all I did was rebuild cylinder heads. When timing chains or belts go and valves bend (aluminum heads) the part of the guide on the combustion side cracks loosing it's interference fit. Guides in aluminum are not integral to the head they are press fit in either cast or bronze. If the machine shop misses that the guide will ride up and down with the valve. Saab's 4 cylinder heads always cracked the guides as did most aluminum heads almost 100% of the time. Did you get a warranty? Did you or do you have to send your old head back as a core?

I understand your reasoning
His latest post above states 30-35K on the plugs FWIW. Assuming they were new when the head was done, he really needs to find the root of the problem, which I think we are in agreement on

270?
Just did a wet test, with another gauage and from left to right 1234
280, 280, 210, 280
I promise, it's a Civic and doesn't have a Ferrari engine in it
Now I am lost, confused and worried

Yes. But it will tell you a lot more than just a compression test.

Unfortunately don't have a compressor
Let me see if I can get one for leak down test.

This is a good clue as to what the cause may be.
HUGE clue!
Mail-order rebuilt heads are from a place like a "sweat shop" or "puppy mill"
The lowest possible quality they can possibly get away with.

I'm going to ask, what was the original reason for changing the cyl head?

That's about 14:1 compression, I cant see how a civic engine can get that high. A couple more points and you wont need the ignition system. LOL
JK, something is really way beyond wrong.
