2uz-fe camshaft marks

[IWRNDU78]

I possibly have a stupid question
I have a just had my heads redone and have been using the Toyota manual to get the correct specs it states that the L head cam dots are 2 dots to middle and R head 1 dot to the middle which I have correct but the Left cam belt sprocket is 180 out and the Right head is correct.
Am I meant to rotate L camshaft 180 after torquing down the caps?
Any help would be appreciated

According to the service manual this alignment isn't for the belt sprockets. This is for the gear drive for the timing of the driving and driven camshafts. The manual instructs you too place both cams with the two dots facing each other and single dots facing outward.
If the cylinder head is installed and you're in doubt may be wise to remove and install the camshafts in the correct orientation.

If you're having trouble getting the cams to line up as you torque them due to the valve springs pushing up you can rotate the crankshaft enough to get all the pistons below the deck height and rotate the camshafts until they align.

I'm running into this same issue. My timing belt snapped so my timing is off. The FSM is confusing with the two/one dot alignment instructions for the cam gears. The left cam pulley needs to be 180 out from the two dot instructions in order for it to line up for timing. Each of the pulleys has 5 spokes, and one spoke has a line notched that corresponds to the the notch on the edge of the wheel for timing marks. The cam pulleys are keyed, so it seems that this is the only way it can go back together. I checked the pistons and they all seem be in the correct position relative to the valves.

Has anyone else confirmed why the FSM has these instructions?

Well, I set my timing based on the cam and crank pulley marks. All is well. Truck runs great. Seems there is only one way to do this, and it's pretty hard to get it wrong.
