They make a head for the big cube guys--its called a Hemi
Isn't Trick Flow Summits house brand anyway? So isn't this a Summit head?
Source has proven that the race to the bottom --NOT the top is the one with the big numbers on sales--at least back when they were $895 a pair
The guys that get back there with an aluminum head that will fit existing pistons/combos etc like the old Eddy/Sidewinder etc will be KING Hey that is a good name for a $795 a pair head
Until then Sidewinders are Excellent quality and get my business--Marsh has been EXCELLENT in providing those heads fast as UPS can bring them and our shop is putting them in about every build we do --
