Headers that DO fit - and DON'T fit.
I have a issue with this; Hooker:B & E bodies W/small block 1 5/8 comp. 1 ¾ comp #5208
Theres 2 headers listed here and the Super Comp header with the 1-3/4 pipe has the wrong number I beileve. It's also listed as "Comp" and that is also inaccurate. There "Super Comp". Big difference starting with the wallet crying after paying. (Cheaper than TTI though.)
The regular Comp headers are the one size fits all design like everyone else makes, so fitment can be an issue.
Another example is the Headerss from Summit racing I got went in with zero problems and zero mods for me while my buddy down the block had problems up the GaaaaZoooo. He only ordered them when we put mine in with ease and his was a nightmare central hub.
