Oil Port#1 for 4G63T

[blesi660r]

Ok i ahead of time apologize for bringing back the dead but I have a Q about this mod:

When doing the port on this how deap do you go, or do you not really go any deaper but just widen
the port like said and not ad any depth?

I would like to do this befor my head goes out to gosh for resurfacing.
