Curious as to what racers, street strip racers on the forum have experienced regards performance of non offset heads. This is a thread to talk about all such heads. The quickest i have personally seen that are available for purchase would be the new Bloomer head. The combo i am familiar with is true pump swill friendly, weighs +- 3200 pounds. 727 trans, 4.10 gear. Has been 132 MPH in summer air. Victor, tti headers, roller cam The car completed dragweek, the combination was brand new, has yet to be fully sorted out. I suspect 134 mph and 10 flat or quicker is in the cards once the combo gets sorted out. The head incorportates 2.08 intake valve, is 200 cc. Takes standard rocker gear. Dont think i know of anything any faster i can personally think of on pump gas Curious to hear what others are aware of, personally with your car or someone who’s car you are very familiar with. Have seen cars with airwolfs, eddies, and trick flows go down the track i have either have or had myself or am familiar with the combo. But the above on pump gas is the best performing that comes to mind Anxious to hear what others have or have seen. edit..not interested in flow numbers, they can say pretty much anything. Just weight and MPH, the combo, ET as well.
