Today, I do a review of what I consider to be the best "AS" cast cylinder heads for the Small Block Ford!
Hammerhead Performance Engines cylinders have really set the bench mark for AS Cast heads. Greg Brown really did his homework as the Stock port flows 395 cfm AS cast using a 2.20" intake valve. Greg now offers CNC's versions that flow over 500 cfm and can be had in both solid Cast or Solid billet forms. This is a huge advantage for the hardcore racer that will be subjecting these heads to massive amounts of Boost or Nitrous.
I give my thoughts of these heads while doing a review of Project MIXED UP BOSS and included clips of old footage as @DavidVizard and myself took these heads from an idea to the Dyno and the engine being installed in my 1971 Ford F100 called Casper!
