new heads

i just got my new heads on this weekend and drove it for the first time tonight, noticed oil pressure is around 60 psi and there is a slight knock coming from the drivers side head, i may need to re adjust the valves, but with the est wire plugged in, it boggs bad at over half throttle. i didnt set the timing with a light, i had it rotated a little counter clockwise of where it normally sits to play it safe, also, my cooling fan kicks on as soon as i start the car, maybe i have my friendly code 15 again, will check codes tonight

Is it a knock or a tick?

Tick could be from improper lash, exhaust leaks or injectors if your EFI.

Knocks are usually from something worse like deto or a bearing.
