90-92 vs 93 b18a1 valve lash
so i have a B18a1 in my car, i am not sure if it is from a 90-92 or 93
i have heard multiple times the valve lash is slightly different from those years.
Q how would i go about determining which lash specs to go by, what marks on the head?
pics, suggestions, comments all welcome!

once again at it again, figured i would switch to head studs rather then bolts
only issue was the camshaft cap bolts one snapped and another twisted like a vine.
4$ and 30 minutes later
