not necessarily
There are many many CNC programs out there. I'd say most of the good ones flow better than a stock LS6 head but I have seen people spend money on no name CNCed LS1 heads and make less power than stock LS6 heads.
TEA makes good heads but I wouldnt even come close to saying the 5.3 stage 1s flow that great. TEA does quality work but even they prolly offer 2-3 heads that flow better than 5.3 Stage 1s. I'd say they are a little better than stock LS6 heads.
