So I have to replace my passenger side head due to broken exhaust manifold bolts in the head that cant be removed. I ordered a remanufactured head and got it in the mail. Issue I'm having is the card that was sent with the head says the head needs to be timed. Now I assume they are talking about the timing of the engine. My plan is to remove the old head, replace it with new gaskets, bolts etc. Now would I have to reset timing? Engine is staying in the car. I have pulled the old head before and bolted it back up with no issues but this being a new head I know it has been resurfaced, new valves, seats, springs. Should I be worried or just install it like I did last time?
