Yep, know exactly what your talking about, I thought I had a crack so I bought a brand new cylinder, lo and behold it looked like the one I replaced. After that I did a closed inspection and determined it was casting flaw, anyway I've been using the cylinder for a couple of years with no issues.

I can see some extra bottom end power just waiting to be unleashed from those lower boost ports.  Cam.

Can be cracks(very common),so weld it if you are gonna replate it anyway.
