well im going to the dealership probably in a week or 2 to pick up the parts for my 6L swap, just want to make sure i dont forget anything. I have to get a timing cover gasket, differential gasket, oil pan gasket, lifters, head gaskets, header gaskets, new oil pimp, and head bolts. am i missing anything here? also should i just get the stock lifters? also, does the type of gasket matter for the heads, im going to put some 243s on it so what type of gasket and head bolts should i get part number wise. thanks fellas
