Have you converted from T&D iron assemblies to the longer shafts plus different washers and tubes while using the rockers from the iron head assemblies,or did you purchase assemblies for GN1 heads? Which ever way you got to where you currently are,you're in the same boat. The T&D GN1 rocker assemblies use the same rocker bodies as the T&D assemblies for iron heads. The problem this creates,because the valves in your GN1 heads are spaced farther apart,is that you need to move the rockers toward their respective valves in an effort to place their roller tips over the centers of their valve stems. You can move the rockers over until their respective push rods rub on their push rod holes and the roller tips still won't be centered over their respective valve stems.
The T&D rocker assemblies for TA SI heads use the same washers as their assemblies for iron heads. He won't be able to use his current washers or tubes. The only things he can use are his current shafts. He'll have to buy washers,tubes and rockers.
No,they're GN1 specific rocker assemblies which use the same rocker bodies as iron head rocker assemblies.
For the third time,you will need the TA SI rocker arms,tubes and washers. The washers used in the T&D TA SI rocker arm assemblies are the same washers used in the T&D iron head rocker assemblies. The tubes and washers,you currently have,will not work with the T&D SI rocker arms.
He doesn't have iron head rocker assemblies. He has T&D made rocker assemblies for GN1 heads. His assemblies use the same rocker bodies as the T&D iron head assemblies. The only useful parts of his current assemblies are the rocker arms to use on iron heads only and the shafts which can be used on GN1 or TA SI heads.
