I am curious if these heads have hit the market yet? They sell them supposedly in different configurations. I wonder what these flow straight from edelbrock in standard form and the difference in their ported versions. I would believe that you as normal would get more from them buying them Raw and having all the machining done by someone that knows what they are doing. Casting flaws I would think are the Normal Edelbrock signature on these heads as well.
