Intake porting was very similar to the street port job on the 2nd
gen. See Mazdatrix site for details. Bottom of Renesis ports have an
odd looking pocket which was smoothed out. This is the area where those
funny looking air injection pipes from the intake manifold go (not used by me of
course). This will probably not have much meaning unless you see it.
No change to exhaust ports.

Tracy, you made an
offhanded comment last Saturday about your “ported” 4 port. Could you expand
on what was done to the ports? Was it both intake and exhaust? Both
internal and external openings? About how much? Thanks,
Herb
