LA cyl head challenge !!
Gun to my head, I would likely pick the reworked Bloomer heads now that Vic has redone them personally. The fact that he did them is all i need to know to place them at the top.
Second choice would be airwolfs. They went 3 mph faster than Trickflows did on back to back tests in very similar conditions on the same car a buddy has. Typical bracket type stroker deal
