Caution here mate, just because the cam pulley marks are out dose not mean the timing is incorrect. When we replace timing belts we use the rear cam locking tool to time the cams correctly and lock the crank with a dedicated pin.
The cam pully is attached to the cams by 3 bolts, the puley holes are elongated which alows the cam puleys to move. This is so during setting the tensioner the load is distributed on the full run of the belt.
To confirm cam and crank correct sequensing an oscilloscope is used to vew cam and crank corilation. Also your compressions do not indicate incorrect valve timing. A vaccume guage should show around 22 hg at idle confirming correct valve timing.
