73 Duster build named Fred
Good news. Engine is out and no additional issues found. Spoke to the builder and the rocker shafts were torqued to the factory spec 17-18 ft lbs and not the Trick Flow spec for their studs which is 25 ft lbs so now I think I am confident I know what happened. New parts are coming (4 pushrods and a half set of Harland Sharp rockers with shaft.) Engine will go back together with the Trick Flow intake as I am sending John the 340 to do his magic and back in the car next weekend. Hopefully weather will get better so I can finish heat cycling the rear gears and get my burnout video.... lol
By the way, look at how good the intake gaskets match up to the ports on the heads....
