High CFM heads - What would you chose?

But how else can you plan a build? Or speculate a possible horsepower number if you can't trust the numbers man :rolleyes:

I understand what you’re saying.
Like with the Indy head example I gave above.
If the numbers from the bench are way off from what most of the rest of the world gets...... they probably aren’t all that useful to most people.

In that situation, they called me looking for a cam.
After he told me what the numbers were.....and saw they didn’t really make any sense for what the heads were....... I ended up just giving his porting the benefit of the doubt that had I tested them here, they should have flowed similarly to other Indy 440-1’s ported to the same level.
