I cc'd the head today. I did two different holes and both came out to be about 45-46 cc's. The head has been milled .100" and has big valves. I'm not sure what average or common numbers are, so I was just running them by you guys to see what you think. Does that sound high, low, average, etc? Also, I found my old compression numbers from when I first got my truck several years ago. They ranged from 112-123 psi. What are they supposed to be? I guess it doesn't matter now that I'm rebuilding it, but I am just curious. |

My head might have been milled before or maybe the took off more than the .100 I asked for but my chambers are 39cc's. My static compression now is in the 165psi range. I believe 130's are new stock? |

I had .100 taken off the head on my valiant. This was an old "blueprinted" stock eliminator head. The head had been milled previously, but could not remember how much. I would guess about .020-.025. So the total would be about .125, and it cc'd at 39

It is also one of the correct details in the Mopar performance book. |
