If you're new to this, you look in exhaust ports and a flashlight helps - you can see both the intake and exhaust pushrod and rocker ends from there. Also, before starting, I fill each pushrod cup with grease. Then when the head is sitting about 1/4" from down, you can lift each rocker into its cup and the grease will hold it there. If one pushrod isn't aligned, it's easy to manipulate it with a thin screwdriver. Once you can see that all are in place you can tighten the head.The workshop manual says to first bring the head down with the exhaust-side center bolt. I do that but I put the four outer head boles in finger tight to act as guides and to make sure the head gasket stays where it belongs while tightening the center bolt and don't go straight to the final torque on any of the bolts.
