My Spiffy clean new head fresh from the machine shop, I haven't even taken it out of the truck yet!.

Top and left you can see someones Supra Turbo intake which was getting the grinds at the same shop.

Here we can see the exhaust side.

It is obviously cleaner and smoother that stock.

You can also see alittle bit of the valve lube (the white gunk) in the opening.

Here is a great shot with interior detail on the intake side.

The shop smoothed and slightly enlarged the passages but left the surface slightly textured. this is to keep a layer of "turbulent air"  on the surface to keep fuel from condensing on the walls, insuring all of the fuel gets into the combustion chamber.

Translation:

Go Gadget... Go.

A close-up of the bowl, cleaned and smoothed, you can sorta see some machine marks from the valve hob. I opted for the 3 angle as it is the one I can currently budget for.
