YNANSB....Google and call around for best price.
Send the heads out for a rebuild, ARP studs, Killer B oil pickup or other proven aftermarket, new oil cooler, verify turbo condition or rebuild at this time. New timing kit, water pump and T stat. Misc hoses, belts, etc.
Just break out the wallet. Depending on your time, skill level and work space you can save a bunch of money doing things yourself. I bought my own parts and had a shop do the work. I'm very happy with the results. Good luck.
