So, I've called, hugger, hedman, hooker, sanderson, schoenfield, jegs, and summit.

I can't find equal length shorty headers for a sbc. Does anyone know anyone that makes such a header? If at all possible I am looking for 1 5/8 primaries.

Equal length provides primary tubes 'tuned' to optimal length for a given application, the main benefit is equal back pressure to all cylinders to 'balance' the VE of all cylinders; and tuning to improve scavenging and minimize reversion.

Shorties (also called block huggers) are designed to provide the least overall back pressure while maximizing fit of the headers in the engine bay.

The geometry of shorty header design precludes an equal length of the tubes from port to collector.

In other words if you have a tight fit use the shorties, if you're racing use the equal length headers and move stuff as needed to make them fit. If you're racing and have a tight fit (can't fit the long tubes); in all but a few cases the shorties will be fine.

Hope this helps.

Hard to believe, you need to look a little harder, practically all the manufacturers you list make them, and Summit and JEG's carry them all.

Moving to Basics.

I called them... I couldn't get a hold of Kooks today. So no they really don't have equal length block huggers as I am looking for.

Now, equal length long tubes. yeah they do.

the only equal length shorty header that I could find was for 5.0 mustangs bade by bbk.

68novass if you have a link to a set, please post it.

these are the bbk header that I am talking about.

One reason you can't find them is because once you bolt on exhaust pipes, mufflers and tail pipes, the gains you might have seen from equal length primaries will be mostly lost. This is especially true of shorty headers as they generally lack collectors altogether.

In any event, especially on a street performance engine, there's no benefit and possibly deficits to using equal length headers, be they short or full length. This is because having unequal length primaries tend to widen the powerband, and while the peak may be down on power from a carefully tuned induction/equal length exhaust header system, the average power/power under the curve often favors unequal length primaries.

Give Lemons's a call, they made a set for Camaroman7D that wrapped the frame rail on his new Skylark ProStreet car, so they'll do anything you can afford to pay for.
