so i dropped off the old 2.8 heads at the machine shop today, they wont be able to get to it until thursday they say. i told them to see what they need, and remove the broken exhaust manifold bolts and mangled intake manifold studs. i plan on doing a 3 angle cut on the valves with some P&P. is there any tedious measuring involved during assembly and can i do this with basic hand tools and picks aside from the valve spring tool? does anyone recomend new pivot ***** for the rockers?
