340 T/A (U code) head value? (Pics)

Do you have the rocker arms?......You need the TA rockers.....or have to buy Harland Sharp aluminum rockers....

I have a friend who has a set of TA heads in plastic bags since they come out of the machine shop years ago....could not get 1000 for them at MATS a couple of years ago...why...NO Rockers..
