ALUMINUM S.B. PROMAXX HEADS ANY ONE USED THEM ?

Go to Marsh Performance and see the heads he is doing. You can't run an Eddy head out of the box. The Sidewinder and pro Maxx make good power. Buy them from a reputable shop that does a lot of them. When you calculate the cost of a complete iron rebuild, the import heads, machined here are a great value in cost and performance.
