providing all of the timing marks are set correctly, you shouldnt need to adjust with the timing light, but double checking is good,
right witht he shims, its easier to remove the cams, but you can buy tools to remove them in situ,
you need to make sure that the valve is firmly seated and not being compressed at all by the cam, then measure the valve and minus the clearance you require,
you can either buy new shims, from toyota or an engine parts shop, or get the current ones machined, if they get machined make sure they are machined from the back of the shim, not the shiny hardened side, other wise the follower will just disintergrate
