About three monthes ago i pulled the head off of my 73' 1800ES because there was a little bit of sluge in the crankcase breather tube. I pulled it off and replaced the head gasket and exhuast/intake gasket. I put the head back on and started the car up to let it idel for 10 minutes to bring the car up to normal temp. Then i tightened the head down to factory torgqu specs, started it back up and it ran really awful. Fast forward three monthes of the car just sitting in the garage, the problem has not gone away. I got the compression, it reads as follows from the front cylinder(front of car) to the rear (towards passenger):
1. 160psi
2. 170psi
3. 158psi
4. 152psi

before i pulled the head off the car had pefect 165psi compression all the way across.

cylinders 1 and 3 both have darkish plugs that otherwise look pretty normal.
cylinder 2 has a plug that looks darker and wet with what may be oil.
cylinder 4 has a plug that is grayish and seems very dry.

I have replaced the injectors (from my 142 that was running well, until the radiator got bite by the fan blade) and the ingnition system from my 72' 142E. The valves have also been set to factory specs and checked three times. I really want to get this car running, please help me guys.
