With all those responses, NO ONE ACTUALLY ANSWERED THE ORIGINAL QUESTION!! Also, don't get me wrong, I appreciate all the pros here who take the time to answer questions, I really do, but don't forget most of us don't own a garage (business) that repairs Vanagons and other VW's. I'm lucky enough to have a garage and a spare engine, but not an extra bell housing, starter, battery, etc. Well, there may actually be a starter buried out there somewhere, I'm not sure. In my case I have a full time job (telecom tech) and with commuting usually put in a 10-12 hour day. Vanagons are a hobby/passion, not a business. Anyway, enough about that. After careful consideration, I think I will redo (new seals) the heads on the spare engine and just swap the engines out-new water pump too on the spare-but no new clutch, that would be a waste of money...mines an automatic. I just have a sneaking suspicion trying to pull the head with the engine in the van will be a disaster and and I'll end up dropping the engine anyway. Thanks!! 

Oh, and I do have a magnifying glass too!
