3.4 valve guide lengths

Does anyone know which valve guide is the shorter one? I had both standard and oversize guides for my 3.4 liter head, and when I got it back from the shop the unused guides were not in any packaging and now I’m trying to figure out if the intake or exhaust guides are the shorter ones.

Diameter is not the problem. I have to figure out which length valve is intake or exhaust.
