Valve?
1st Thing I would check?
Coil Bind on the Rest of the Valves?They DONT jsu Break,for NO Reason?
Who set the Heads Up?
I would'nt see why the Head cant be Saved?
I have had them come apart at 9000 in the Lights and,a little Dye Grinder Action,Some Alu.Tig work,a few New Seats and Valves.And back at it!
If it broke at a Idle,IT CANT BE TO BADDD!
Later
