Before you remove the cams. Take one of the bolts that hold the Cambelt cover on. And ther is a hole on camshaft pulley. (Inside) basically the cog that's turns the other cam. You have to put the bolt through to stop the back of the cog turning. If your gonna reseat all the valves. Remember you have to check you tapped clearances and they are solid. Not hydraulic. You can get updated stem sills from zisco. Here is a link about the camshaft bud http://www.toyotagtturbo.com/forums/showthread.php?100863-Cylinder-head-removal-and-installation-info Hope it helps
