When I am reading about tuning everywhere they mention steel ball on the flywheel to the pointer on the bell housing. I have seen a triangle on the flywheel pointing to my pointer now and I set the distributor rotor to point to 6'0 clock positing by moving in the insider rotor shaft mount with a screw driver. The only thing I ever saw on my wheel is a threaded hole other than triangle pointer. Is that what is referred to as steel ball or my steel ball fell off?

Is this all I need to tune

I gave my exhaust manifold and intake for resurface as there was a gap from the head to manifolds.

Please share some info
