Sorry, I missed the "but" in your post and read it as "Don't buy any long tube..."

Shorties are only marginally better than the iron manifolds, and medium length are better - but less than the full length.

Cost is close or the same on all three.

You'll only need smaller tube headers if the engine will be stock.

If you'll be lowering the truck - try to use the med length.

Good Luck !!
