I have Beyea headers on my 604 crate car. I have not dynoed them or any others, but they sound great on my car and my motor seems pretty stout compared to other crate cars on the track.
So brad with your post and your experience which headers do you recommend, not including the headman? The beyas
Have gotten a reputation of cracking, do you agree?
m.lion, I have had 2 sets of beyeas and they both cracked. Once I would fix them they would just break again in a different spot. I did have them supported with hangers. Ran a set of the new style schoenfelds this year and they have yet to crack. I can't really tell a difference as far as power goes but I would recommend them.
Hedman is best hands down we have their original set of tri-y's they done for our mods and have over 200 shows on them and still going strong. If they do crack or get damaged send them back and they will fix them within reason of course if the whole thing is crushed it was not their fault it cracked. Everyone we have sold them to loves them. you can get them through my shop 573-330-8462 or call direct and ask for Chris.
