And how would you know that the ported stock heads suck? Have you ever tried them? And as far as Edelbrock's offerings, there are much better heads out ther than them and the difference is like night and day over the E'brocks. Nothing at all wrong with ported iron heads when you're on a budget and can't swing 1000+ dollars for aluminum heads.

if you can get a good set of ported stock heads it is possible that they could outflow the e'brocks. www.powerheads.com has early castings that are cnc ported with 1.94 & 1.60 valves screw in studs and guideplates for about 650 bucks, there is a guy named fletch or fletcher or something that has a flow chart comparison of several different heads including the power heads and gt 40-p's and e'brocks as well i think, anyone have the link to his website? i lost all my bookmarks when my hard drive crashed a couple months back

Take it easy there big fella........

It is called flow bench testing, and also real world experience!


Check out www.fordmuscle.com's head flow comparison......it will open your eyes. Big thing to remember is AVERAGE FLOW rules the street.....not peak flow! Despite what you might think.....even the old Edelbrock heads do VERY WELL with all the others including AFR and TW when you look at average flow!

If you are talking all out race heads.....WHICH WE AIN"T....ya, there are real wild ones, some of which are made by Edelbrock.

Now, when a machine shop that rebuilds heads tells you: not to bother redoing the old stock iron heads...........that tells me something: mainly that you can take irons out to the level that the aluminums start at.

I rest my case.
