The flow gains are almost unbelievable, but as most people know, numbers aren’t everything. We need to get the port finished, then digitize and CNC it and try it on a car to make sure drivability doesn’t suffer.
From your previous post, the Intake Flow increased 110 CFM That’s a 60% increase.
The Exhaust flow increased 37 CFM or around 25%.
I’m impressed!!!
Get those puppies on a car!

UNRELATED to the heads in the above link because they are not on the market just yet…
a gentleman by the name of EcoBrick Bob has been all about going fast in the SHO community and it always cracks me up when he posts his 1/4 mile time, and not because he is racing this MASSIVE vehicle but because it is really fast!
WORLD’S FIRST 12 SECOND FLEX 12.901@106.85 MPH
He just bought slicks for it. He only put the fronts on for comparison for this pic.
I will dig some up tomorrow. Those heads would be nasty on a F150. I forsee broken rods once turbo upgrades happen which are also in the works as well as fueling upgrades.
I have a few customers who have the new F150 with the twin turbo ecoboost and they can tow 11,000 lbs. +/- with an oil cooler. That is pretty insane for a 1/2 ton truck. I have customers struggling to get that out of their 3/4 ton trucks…
