new absolute stg2 6.0l head flow numbers Finally have the 6.0l cnc program up and running, It is a different program than the ls6 even though the ports start there lifes identical from GM. The 6.0l port was designed with the best lows and mids found on a gen3 head today while peaking close to my ls6 head, I still recommend ls6 heads for larger xer type lobes .600 and over my stg2 6.0l head will maximize potential power with more mild lift cams in the .560-.590 range. The flow numbers are as followed on my superflow bench tested at 28 inches on a 3.9 bore

I should have the new set of 6.0l heads on my car real soon. These heads done with lower compresion are excellent for forced induction cars as well. They will also work awesome with stroker motors and big bores.

All heads get the new blue viton seals as shown on my 2.5 section of my website. The valves are revs. the springs are comp 978 or 977. Int Runner volume is 225cc's. They flow very well through an ls6 intake and really love the lsx. I will add the intake flows in a day or two when I bring hame my flow book.
