As ARP doesn't offer a complete kit you will need to buy each part separate.
ARP part numbers are:
2 of ATP7.675-1LUB
8 of ATP6.350-1LUB
10 of 7/16 12pt nuts
10 of 7/16 washers

These are a fantastic product and I could not recommend these more highly.
The distance from the seat to the top of the center stud is 16.5mm. This gives 5mm clearance to the cam.
The torque spec for the ARP studs with ARP moly assembly lube is 62 ft/lbs (I went 3 steps...20 ft/lbs, 40 ft/lbs, 62 ft/lbs)
Just an update.
The new engine is in the car. Studs torqued as listed above. On start up the engine ran OK. I took it up to temp and then left it overnight. In the morning I warmed it all up again with the intention to tune it. HOWEVER. Coolant coming out the exhaust is a bad sign. Turns out the copper gasket was leaking somehow into a cylinder. There is no sign of this on the gasket. I ripped out the copper gasket. Replaced it with an OEM Honda issue item and re-torqued the studs to 62 ft.lb. I've now run about 40km on the engine no issues.
