I had the head rebuilt on the 51 WD. After I assembled it, I would like to know what the clearance are for the tappets when they are cold. All I can find is for when they are hot which is .012. I had them adjusted to .012 cold when I warmed it up. I now am retorquing the head and I want to reajusted them when it is cold. What do you set then at?
