Heads that are done by cnc

[95rayburn]

When you get a set done by the cnc machine shoud you have to do any work to the bowl area around the valves

You shouldn't have to. However some builders take it a few steps further and do some handwork.

a lot probably depends on fuel being used, and how smooth the CNC program was in the cutting process.

gas you could smooth up a bit with a pointed emery paper style tool
Alky or e-85 you an leave a little more on the rough side to keep the larger amount of fuel running through port atomized.

depends on engine builder preferences really.

Thank you. Much better answer than mine!

Cheap heads sold with a cnc port often only get a basic port match plus. A good program will do the bowls, too.

Have yet to see a CNC head that could not be improved with a little hand work
