Anyone here ever had their head flow bench tested. Perferably the 2.4 2rz. Anyone?

Hell the truck sits all winter and I'm going turbo so I wann be right on with my numbers. I'll have to see who can do it. Then I'm gonna port and polish for some more flow. The crazy part is that neither LC or EL have done this either. I would think with all that heads they have so R&D would be in order.

yeah i have asked many times the same question......but seems the answer is no need to port and polish unless you oversize the valves......then in that case their is no point unless your building a high reving motor.....but let me know what you find out.....many flow benches out my way......good luck...with turbo i dont think a port and polish job will helop hardly at all......what will help most would be get rid of those 14" runners we have on the intake manifold.....that is where our spool time is goin and lag time is increasing.....ridding of that will help the most.....our intake bore is smaller then the head port so porting the head would be only as good as the smallest point which would be the intake runners so unless you change your intake somehow then i dont think their would be any point....but if you do flow it let me know some numbers so I can change my setup around.....
