If he didn't use lube deff buy a new headgasket and reinstall it with the lube my car ran like crap and i forgot to lube the threads. We pulled it gasket was wasted and also won't get the proper torque on the studs without the lube which would explain why each cylinder is different and seal up those oil leaks

So pulled it apart and what do I find?? All pistons had at least 1 ring clocked wrong and 2 pistons had the 2nd ring upside down!! My god great friend huh? Cylinders still look good thank god and hone is still visible. Head and block were still straight but 2 exhaust valves seeped a little gas when I filled them up. So im taking it by the machine shop tomorrow. Thanks for helping....I will update as I go

Alright so I FINALLY got it back together. First I had to wait for the rings, and then while torquing the head down I pulled threads out. Its not the first one that has done that to me on this block. I had 3 holes previously do that and I had a shop install time certs. This time I had the money for the kit and no desire to pull the block again so I bought the time sert kit. I installed in 5 holes and the two in the middle I left alone. So anyways, it runs great so far. I started it up and let it idle for avout 20 mins and during that time I adjusted ignition timing and bled the air out of coolant. Shut it down and topped it off, and went for about a 10 mile drive. I would take it to about 3.5-4k rpms and then let off the throttle and let the engine brake. I will continue to drive in that manner until the rings fully seat. Thanks to anyone that helped me throughout especially wunfstgsr.

I have one more question... when I adjusted my ignition timing, I warmed the car up completely, jumped the service connector and shot the light down at the crank pulley. Ive set timing on my cars plenty of times in the past , but this time when thee distributor was in the middle, it was a good bit retarded. I turned it all the way towards the front end and it is still like 4 degrees retarded. I checked my cam timing and its spot on, so the only thing I can think is its because my head and block were resurfaced. Does anyone know how I go about checking this and also how to adjust it with adjustable cam gears. Or is there any other reason that could cause this?
