Thought I'd give an update here. Before starting this head and cam swap my engine had developed a ticking noise in one bank and was not producing quite as much power. During the tear down, I pulled a push rod out that the ball end had collapsed back in on itself making it way too short.Piston tops are clean and bores look good. Recently changed the rear main seal (It was installed backwards!) and the rear main bearing looked great. As best I can tell the engine was recently gone through and has std bore and standard main bearing diameters. There was no ring groove at the top of the cylinders, so I have elected not to rebuild the bottom end at this time.Still need to check valve to piston clearance as the new cam has .570 lift, but with factory dished pistons and stock valve sizes, I'm expecting to have plenty of clearance.Hope to finish up getting everything back together and tuned as well as getting the headers hooked into the exhaust system in the next few days.
