What non tri y headers are the best for a 604 crate motor ? Has anyone found HP gains with different make headers? I am new to late models and don't have a dyno or the funds to test all different make headers. Thanks for any info

The beyea headers help some, mainly a little more torque, but after running beyea's and dynotechs its hard to justify the 600 for the beyea's
