Low Compression

[Tom Walker]

Get a hand seat cutter, see if she ll come back to clean seat in that worst bit, grind in the valve and get on. That all looks fine to me, the corrosion is around the water holes is just where gasket holes are bigger. Be careful to not disturb too much crap, and use old gasket. If yr short of dough at the moment you cant do any harm, get er back on the road!
