HEAD TO HEAD : Edelebrock stage 2&3 craft performance

Edelbrock is one of the older names in the aluminum FE head game. Starting in the late 90's they brought  aluminum FE heads to masses at affordable prices . Since then builders have ported , ground , and CNC'd in every way imaginable. The work on these heads sets the bar pretty high.  They were sent to us by Craft Performance  and represent his Stage 2&3 offering. Many thanks to Lance Smith at Craft Performance for sending these in for us to test .  As with all our test they were performed at Cleveland Performance Center on the same  Superflow 600 @28" .  These heads are very impressive and available from Crafts website .The  stage 2  uses a 45 degree seat , the stage 3 becomes more aggressive with a 50 degree angle to bring more flow through  smothly. On valve sizing the stage 3 increases the intake valve from the stage 2  size of 2.190 to a sewer sized 2.250. With the flow of these heads power potential is very impressive . For street performance or a dedicated race program they have an option to fit your need.
