Head flow and power differences question / discussion

ch1ll said

Just a few ideas to consider from my limited porting knowledge and lack of real world experience.

Cfm is only part of the story.
Port efficiency comes into play.
Your air speeds throughout the port, as in no dead spots.
And there are more.

Your intake manifold is going to be your choking point with either of those 2 heads. You would have to flow the combination together and compare both choices.

With heads that flow in that range, I believe a tunnel ram would be your best choice.

I have read and talked to others a little about airspeed and intake flow as well.

I appreciate your input, my current choice for intakes is what is making me second guess which heads to go with.
I have the Indy single plane they sell with the heads. I also have a Trick Flow single plane which would work well with those heads. I have a six pack setup, and the tunnel ram that I have been running for a few years now.
I've been thinking more about staying with the tunnel ram and selling the others.

Thank you.
