I talked to Ron at ARP and there is no kit for the TTA, just measure your old bolts and order them.....What I just had to do for my torque plate and I have to do the same for my tta heads when all my extra machine work is finished....
If you are talking about champion GN1 heads, there is a kit available....
with stock block & Champion GN1 Heads #223-3705
with stage 2 block & Champion GN1 Heads #223-3704
Hope this helps
