M103 - Compression Test Readings

I've have had some problems after installing a used Brabus Cyl Head onto my car. Basically, the engine eats oil, spark plugs foul up after a week or so, which causes misfire. On 3 of the spark plugs, cant see the tips at all... all covered with carbon. Also, I am experiencing loss in power recently.

Today I did a compression test and got these results. Not sure if my technique was correct but I let the engine turn about 7 times. Hopefully someone can let me know what's wrong with my engine.

Dry Test
Cyl 1. 135 psi
Cyl 2. 135 psi
Cyl 3. 85 psi
Cyl 4. 105 psi
Cyl 5. 145 psi
Cyl 6. 90 psi


Wet Test
Cyl 1. 140 psi
Cyl 2. 145 psi
Cyl 3. 95 psi
Cyl 4. 110 psi
Cyl 5. 150 psi
Cyl 6. 95 psi

I believe the Brabus Head increases compression and hence is breaking up a 120000 mile old engine. Your views pls.

Thank you.
