Thanks. I am assuming the numbers are as received from Brodix?

Are you planning to do some work on them? I would be very interested for a set that were set up to increase the .400 - .600 performance even if that meant the .700 and up numbers were sacrificed (VJ angles, etc). Any thoughts?

(Not to say that the mid lift performance is bad in any way.) Just looking at these vs a high port and other heads.

No that's my program. We bought as-cast castings. The bigger valve flows more in the middle for sure.

The Brodix CNC heads were nowhere near this.
