headers for a 604

[macri28]

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

beyea has the best header for crate engines we have dyno tested them all and beyea has better results
