Factory Head pipe Dimensions Needed!

[cspaghetti97]

Does anyone have a headpipe or manifold laying around that could take some measurements for me? Either with calipers or micrometers if possible, was hoping for something a little more accurate than a tape measure.
Thanks

I think I have a green gasket and calipers if that would help

A = 1.625

B= 2.900

C= 3.690

C2= 2.900

D= 2.890

Best I could do with a new green gasket

Edit: just noticed your C is not the hole center.... I’ll recheck it

Ok I corrected it... I added a measurement you didn’t ask for, it’s C2

C2 is the holes “center to center” along your C line
