Whatever you do, don't forget that there may be bits of metal in the oil. I would flush the systems.
Change the filter also.

My uncle runs a fleet of trucks and his company always flushes new/repaired engines by running
diesel in place of oil for15 minutes. Then draining and replacing with oil. Then running for half an hour then
change oil again. They claim with this process they clear crap even from new engines. Most of the fleet
last for a minimum 10 years of hard hauling and they have minimal engine issues. I heard this technique
from another mechanic who specialised in recovering engines that had seized. But I would seek a professional
opinion before doing it myself.

Concerning new heads, They will set you back about US$1500 all up with gaskets/new head bolts/ARP studs coolant etc.
If you can pull the heads yourself, I would think you can get those studs pulled and the holes drilled and
tapped and some ARP studs fitted for a few hundred bucks. Might be the best solution for a street car. Also
the valve head could possibly be machined.

Pull the head and take it to a shop for repair.
