Engine reseal suggestions (possibly cam too)

Thanks everyone. That is a lot of good information. I guess I'll have to figure out a budget and go from there. Originally it was just going to be to fix the massive oil leak which looks love it was caused by a ba pan gasket. Went and changed the oil and it wouldn't even hold the full capacity atleast a quart just leaked out the back. I just don't want to go overboard on it and not be able to afford to put it all back together for a while. So it looks like there is a couple votes in both directions for replacing the head gasket and not fixing something that isn't broke so I'll look into what it'll cost to get the head milled and see how that'll fit in my budget and go from there. Thanks again for the suggestions
