Stock valve CNC heads, big flow on a budget

[Kenny]

Okay guys I have stock valve CNC heads available for $500 assembled with your stock valves and springs. These things flow an astonishing 350+ CFM.

These are special built to be fully upgradable to big valves later (for a fee of course). This port is capable of well over 380 CFM with +2 Ferrea valves.
