You shouldn't attempt that job without the manual. Also be sure you have, or can get, a torque wrench and a timing light before you start. Be sure to label all the wiring and vacuum lines so they go back in the same place. Match mark the distributor to the block with a sharpie so it goes back in close to the same position.Drain the coolant before removing the intake, that should keep most of it out of the engine. Also be sure you clean out the cylinders real good before rotating the engine with the heads off. A blow gun works good for that. I ruined a 360 from spinning the engine with carbon that I cleaned off another piston that got caught under the rings and scratched the cylinder wall. After you get it all back together, change the oil before starting it.
