I haven't looked at out cam profile so I'm assuming a lot. However, since I made no real power it's obvious to me we have no overlap to speak of. Impressive flames didn't shoot out of the open headers at the end of the dyno run. No overlap. Have a real detailed talk with the header designer, show him my photos and tell him my results is all I'm saying, before getting too far into this venture. Have him take a look at out cam profiles. If after all that he's sure, go for it and I'll rub a rabbits foot for success. All I want to know is how in the world are the E55 guys getting 70 hp from headers. (thats what sold me BTW)
