RE: thumper heads
the stock E7 ported wont hurt youre 60ft times compared to stock. only compared to an aluminum head. and the thumper heads use stock valve size so they have plenty of potential if you want to upgrade. the powerheads, use 1.90 intake valves which is larger than stock so they flow very well. the price of the GT40X are a whole lot more than either of the ported E7s. and out the box dont flow nearly as well. just something else to think about.

I actually live about 10 mins from orangepark!!
And anyone that is everyone i know of is running thumper heads, its not just the porting and polishing but the 5 angle valve job done on the intake side to create the massive low lift numbers. regardless of the extra 45 lbs these heads are extremely hard to beat for the price that you pay for them vs. aluminum.
