The few xtra I have will fit your engine. You will need an intake gasket set, 2 valve cover gaskets, a carb. base gasket, and a 3/8 inch ratchet set with a 9/16 and a 7/16 and a 1/2 socket. And you will need a 1/2 in wrench. Should have a torque wrench but plenty have been changed without one. Remove the spark plug wires marking them so they go back in the correct locations. Pop off the Dist cap with the wires still attached. Remove the 5 7/16in bolts holding on the valve covers. both sides. Remove the Carb. remove the PCV valve from the valve cover. Remove the valve covers. now take out the 9/16 inch bolts holding on the intake manifold. You will have to pry it off when ALL the bolts are removed. Might need a wrench to remove some. Nest remove the 1/2 in bolts holding on the rocker arms. lift off the rocker arms making sure to keep them on the right sides, dont mix them up. Now remove the push rods, now remove the lifters. Re assembly is in reverse order. Lube the new lifters with correct assembly lube. Replace all gaskets with the new ones. Do not over tighten the valve cover bolts. tighten the intake bolts per pattern and torque to specs. Tighten the rocker arm bolts evenly so you don't tweak the shaft. Torque to specs. Im sure I have missed something but that is what you will have to do to replace the lifters. Clean everything you remove, you cant be too clean.
