A new head is the expensive part, top and bottom rebuild kits run roughly $500 total.
One thing I did notice, the front lower engine mount bolt gets pretty coroded. Being as these bolts have no seals, liberal waterproof grease is in order when I reinstall them.
Swing arm does that too... In fact it kinda surprises me that you had a problem with the front bolt and no mention of the swing arm bolt. Some people use an anti-seize compound, but a good greasing does the job.
I am not sure how you define a "top and bottom rebuild" I've got about $1000 in the crank, main bearings, piston, cylinder, gaskets, seals etc. That is still cheap when I compare it to my Huskies (bare crank is ~$1200), BMWs or KTM.
The head that I have built is worth about $1100 in parts (no core purchase) to initially build and about $200 to rebuild later, but that head is built for a stroker which tends to blow out the top end cost. You could probably get it done for a heck of a lot less with a set of Hotcams and reusing many of the parts that I have discarded.
