Racing flow benches

Great thread and very enlightening indeed!

I have read many, many articles on iron heads over the years.
I guess folks don’t want to spend 40-50 hours on a head to get worse flow?
So benches can be (possibly) manipulated to show good numbers (for a customer) lol.

200cfm @ 300 lift is my new mantra lol.

As they always say “the valve only sees max lift once”
Everywhere else it sees Twice...
