Everyone:
As I have suffered through a motor build for the past 6 months, I figured I should share one of the biggest surprises that I've come across.
I had a huge problem with my TOG headers leaking once the new motor was installed. Not that the fit/alignment was evr very good anyway, but by this point they had been removed/reinstalled so many times that they just wouldn't seal. I am convinced this has been the source of my headaches.....so I wanted to share my findings, since I received a brand-new set of (raw-they will get coated soon) S&S headers today, and pulled off my old TOGs this evening. Check this out:
Here's a shot of a S&S primary. Like the D-shape to match the exhaust port on the cylinder head?

A better shot without the flash:

Here's the stock exhaust gasket (okay, a cut-up one) held up to the S&S primary. Size matches perfectly.

And here's the same gasket on the (round) TOG primary. No, that's not a shadow....the primary is much smaller than the gasket!

The front header is actually pretty close between the two brands - primary lengths are only about an inch or so longer on the S&S, and longer is better. The S&S primaries range from about 13.5" at their shortest (cylinder 6) to 21.75" at their longest (cylinder 2). Collector length is longer on S&S also at roughly 4"; TOG is only 2.5" long.

The difference in the rear header is more obvious. The TOG rear header is on top of the S&S rear header here:

Here's some measurements I took. I measured the primary for cylinder #3 only, which is the shortest (cylinders 1 and 5 are about 2-3" longer on both):

The TOG primary is only 8" long (with a puny 2.5" collector length)....
While the S&S is:

12.5" long with a 3.5" collector. BIG difference!
For the downpipe/flex connection, I really prefer the simple 3-bolt flange of the S&S (no slop in the bolt holes; they line right up) over TOG's more involved 2-bolt flange (which can be more difficult to line up straight - the holes in the flanges are oval, which allow for some adjustment):

Last but not least, we come to the outlet of the flex section. S&S is a smidge over 2.5".....

TOG is only about 2.25".

Any questions?
