Depending on the details that only your engine builder has, and the power you make, I'm going to say 1-7/8" to 2" step headers, around 34" long (17" long each step) and a 3.5" collector about 17" long. Again, that's an educated guess, it is probably a bit on the large and short side. But without knowing a lot more, it's hard to say. You could go with 1-3/4" to 1-7/8" and maybe longer, due to lower HP and RPM than the 375 combination.

Having had Hooker, Hedman, Lemons, and Stahl, I can tell you that Stahl is the only choice, nothing fits better, nothing works better, and you'll spend the difference in price making a lesser quality header work.

If it were a street car, or a bracket car, maybe you'd want to compromise. But not on a class car.
