Hi Gary
What does this mean "2) Block off PCV valve-done" ???
You plugged it up???
I have the Z304 heads but only bought the bare heads. Then built them up from there.
They seem to be really good heads. Not sure what they compare to though?
Makes plenty of power. No Smoke. I asked Mark when he was following me the other day. We got on it pretty good about 100 times
