Are these the Merlin heads that you were going to sell that were left in a shop for a while?????????UnsureI have no clue I will get casting # and post tonight. They came off a blown motor with 4-5 lbs of boost I had them gone through then I ended up buying a pair of merlin heads so I would like to get rid of these.
