Header Size Recommendation

If you bought 5204's those are good headers that you have to drive carefully because of a tube or two hanging low.

Those shorties will choke the crap out of an engine making any power.

That engine with a good tune should run high 11 in a great chassis. Make it HOOK! Maybe better. Get the tune up right! If you ran Stock class stuff, you should know what it takes to make it hook. :)
