Questions & Answers

Would these fit headers for a 304 V8? It appears that they would. ?

Headers are universally the same size at the collector as long as the collector bolt pattern is 3 inches. 5, 3. 0 or 3. A 3 inch is taken by the vast majority of people. As a result, they should fit in most applications; hopefully, this helps.

What is the thickness of them?

2 inches or 5 inches 08 mm

Does anyone know if these will fit the QTP 3" exhaust cutouts?

Cutouts are the same as collector mounting, so if you know yours are 3 inch, they should fit.

What are the 3/8" center to center hole measurements for the sce gasket 4300 3" copper collector gasket? What's the difference between 3 3/8" and 3 1/2" in length?

THEY ARE COMMONLY EXTREMELY DETAILED IN THEIR MEASUREMENTS. IN ANY CASE, THE COPPERS ARE NOT THE BEST! WAY TOO THIN! CHOOSE ONES THAT ARE THICKER!

It's a great way to fix a leaky collector
5/5

I had to rework the exhaust system in my 1979 Ford F350 pickup after changing the transmission from a C6 to an E4OD. My truck has a set of headers as well as a nice 3 inch exhaust system that has been on it for the past 18 years. The collectors had never been unbolted and had never leaked, but the exhaust pipes had been reworked and were leaking profusely, so I decided to try these dead soft embossed gaskets. They are very effective, and there are no leaks any longer. They're made of soft metal, but they work because of an embossed ring around the flange where the pipes meet. I loosened everything, took out the collector bolts, slid the gaskets in place, and bolted it all back together. I'll double-check the bolts for tightness after a few heat cycles, but I don't expect them to blow out like a standard header gasket.

This is an incorrect description
3/5

The description of the product is zero. This is not the case at all with a thickness of 25. They're only a tenth of an inch thick. If I had known they weren't 1/8" thick, I would not have ordered them. This was a complete waste of time and money.

They were successful

After a set of aluminum gaskets burned out, these copper ones were used to replace them. These were effective.

Gaskets are in excellent condition
5/5

With these, I've had a lot of luck. They seal well and, more importantly, they last; in fact, you can disassemble them and reuse them. They also leave no residue and are easy to remove from the pipes. These are fantastic!.

The fit is perfect, and the seal is effective! Make sure everything is in place before sealing
5/5

I don't know what else I could ask for in a gasket. I went with copper because I expect these to last longer than the standard units available. These will be installed on a 1970 Chevelle with a 496 big block and 3" exhaust, and the car will be driven for about 1000 miles per year, so they should last a lifetime.

These are the best collector gaskets I've purchased in a long time
5/5

They arrived on time, and with over 43 years of experience in the industry, they knew what they were doing. I am impressed, as a shop owner myself. It was very easy to seal.
