How to turn Yourself into a Human CNC Machine
a CNC Machine with all the Tooling/Fixtures cost hundreds of Thousands of Dollars !
and for a very small $ Price comparison , you can accomplish same accuracy + results
with a Vertical Mill + Goodson 3D Cutters + 0.090" or 0.125" thick aluminum Templates .
no matter what and how the CNC Machine Ports the Chamber and Ports
it all comes down to performing the very "critical" Valve Job !
Using Goodson 3D Cutters is akin somewhat to a CNC'd Valve Job !

Trim the Brim off these FREE Hats , so i can get the Grinder's Body closer to my Head
for better angles when Porting in the Bowl areas .
The Chamber 4.010" Bore Template is so that a Scriber can markout a 4.000" Bore circle
for STD Bores .... and i have other size Templates
and also use various Copper Headgaskets w/round Bores for same reasons .
I cuttoff the Valve's Head and use just the Stems as a straight-edge
to align my Bowl Templates against .
I made various Stem diameters ,,, like for BBC Heads ,
i would have plain 3/8ths, then 3/8ths with reduced to 11/32 if i converted guides to 11/32
also had 3/8ths to 5/16 if i converted 3/8ths to 5/16 Valves
and likewise a bunch of these Valve Stems in various diameters .
i knick the Valve Stems around in a few places in same plane ,
so when i insert the Stems into the Guides they do not fall thru !
