Cylinder Head Porting

[fitzi_74]

Hi i'm new. I am currently starting a Cylinder head Porting project. I have previously ported an 8V VW head very basically. The head i will be porting now is a 16V 1.6 Zetec. I would like some advice on how to get the best flow throught the ports. I have acess to a Superflow Flowbench and all the tools required for porting.

Heres some moulds i took.

I am assuming this is being done manually with a die grinder and long reach burrs, stones and drums? Or are you CNC porting this head? I always just do a quick and easy gasket match port and polish job. Worry more about smoothness than port size to maximize flow.

The castings are cool, are you just using them as a guide for your port job?

This guide is old, and I like using burrs better than grinding stones and sanding drums, but I think it is a pretty good general outline.
