Well, blew the stock aod transmission a few months ago and with kids and work just kinda put the stang away for a while, finally decided to get her going again and bought a built aod for it, I decided to pull the engine and tranny so I could go ahead and replace the rods, mains, and head gaskets. Well got the top end off and found this, is this repairable? Engine was running perfect with no issues, glad I found it though. Any suggestions? Would it be easier to just buy a bare head and transfer my valve train over?
