Re: el head gasket
Guys, can I give a bit of advice. I would never, never refit a cylinder head without having it checked and at the very least milled by a professional head shop. You don't have to have the valves done, or the head welded if it's OK, or if cash is tight. But it should be checked and milled to make sure all old gasket metarial is removed, and any slight warping or imperfections in the mating surface are corrected so that you have a completely flat and true mating surface. Only a few thou need come off. For the block surface, clean it off with a scraper and finish with a stainless steel scouring pad and a drop or two of kerosine to clean off oily esidue and prepare the block surface. Then blow down everything and finish with a clean rag.
Given the frequency with which Falcon head gaskets go, and the time and expense you are going to to do the job, a quick trip to the head shop can't be emphasised enough. Go to it! I've done heaps of heads on lots of cars. This is the approach I use and I've never had one come back.
