A bit of side by side perspective... port on left is #3 completely roughed out, on right is #4, has yet to be touched by me.

A slightly different perspective on the same 2 ports, this time from a more revealing angle



apologies for the less than perfect view of the crappy port, especially as the ported view is pretty clear... What can be discerned is the untouched port (right) has an amorphous blob in the lower right of the port, not seen(now removed) in the much clearer view of the ported port. Also note gasket fitment, the right hand port will give up about 1.5mm at the gaskets surface, but the interior gives up even more. The cross width of a standard smallport is about 44-46mm, the cross width of these ports is now between 48mm, and 48.25mm


The 4 intake ports are now mostly to size, there will be some changes as they are additionally blended after the O/S seats are installed
