Initial Plans Were To Have My O.O.T.B Edelbrock Heads CNC Ported,But Wondering If It Would Be Worth The Cost Right Now Concidering I Am Only Using The MP 528 Solid Cam & Is Strictly A Street Machine Not Seeing More Than 6000rpm.

It will not make as much HP, but it will be enough to put a smile on your face, especially on the street. you can save the porting for a future upgrade. OOTB Eddies will surely be enough for the traction that you will get out on the street.

But anyway you should run good with the OOTB Eddy RPM heads. I ran 11.40's @ 116 with a 440 and 906 heads at 3700 lbs with my old combo. Good luck with it , Ron

This usually (and should) include check and touch up of the valve job, check and touch up of valve to guide clearance and quick clean up of ports and bowls. Over .5" lift most folks will want 10 degree locks as well. Cost is much lower than porting and its cheap insurance.
