Head Porting Advice

First of all--great job on the bowls, it looks like you have removed alot of iron and that really picks up the flow. Second of all get them on a flow bench! All of your great bowl work will more than likely overload the short side and you will have turbulence that will set in at (WAG) .530" valve lift, this will require going back and forth between the pushrod pinch and the S.S.. With that being said don't worry too much the EQ Mag's are hard to mess up, they always seem to work great. I have written a CNC bowl porting program that nets a flow rate of 270cfm with no other work other than valve job. I also wrote a CNC intake gasket program that gets a true 1.000" through the pushrod pinch. The result? After blending all of the material where the CNC stuff leaves off--277cfm --huh? Well then the S.S. became critical, so after that is worked properly I saw 291-300 cfm between all 8 ports @ .650" I figured that was good enough for what the goal was. J.Rob
