It's not that tough of a job. Disconnect wiring and air intake, loosen serp brackets and slide 'em forward on the studs, mark and pull the dizzy, pull intake and go to town. I use a bead of RTV across the front and back, don't go overboard, a bead about the size of a pencil is generally plenty. Make sure you get the FelPro gaskets with rubber inserts, most parts stores are familiar with 'em. Plan on an oil change, I usually wash the lifter valley down with solvent and change oil right after I finish the job.
I wouldn't wait, if a decent amount of coolant gets into the oil it'll take out rod bearings. Seen it many times.
