heads question
heads question CNC ported heads... is that a brand...is that how they port the heads... what does that mean? and bout how much power can someone expect to gain out of working 5.3 truck heads???
From Wikipedia.org:
"The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives a machine tool, a powered mechanical device typically used to fabricate components by the selective removal of material. CNC does numerically directed interpolation of a cutting tool in the work envelope of a machine. The operating parameters of the CNC can be altered via a software load program."
Are these heads straight off a truck or have they been ported?
