Don't be nervous. Slow, careful, clean work is the rule of the day. Do yourself a favor though. You have the motor this far apart, go a little further. I think you are working with a 55 block. Pull the side cover. There are two oil drain back holes (in between the lifters). Plug these up with corks or something. Then carefully clean the top of the block. Then, pull the steel line that is behind the cover and clean it out really spick and span. Take a close look at the boss at the rear cam bearing (where the lower part of the line was installed). Make sure its not clogged or restricted. If it is, gently clean it out. When you get the head back from the machine shop, scrub it up nice and clean. Pull the hex plug from the side of the head and make sure the boss at the underside(where the upper part of the line was installed) is clear right up to the top of the head. This is the oil feed for the rockers, the hex head plug is a direct path so clean it all out. This is where the restriction is generally found that limits the oil feed to the rockers. Gum and built up gunk. Scrub the rockers clean. Having the rockers rebuilt is expensive so you want to do all that you can to keep them supplied with oil (not to mention the oiling feature for the rocker tips and push rod cups, and the cooling feature of the oil on the springs). Clean the cover, new gasket and you are all set. Remember to remove the plugs. I like to use a little speck of white assembly grease on my push rod cups and rocker tips when reassembling.
