Impressive Gasket for High Performance Cars

The Percys Header Flange Gasket exceeded my expectations! Based on my observations this gasket provided a perfect seal and improved performance of my car. The fit was perfect and installation was a breeze. The gasket is made of high-quality materials and seems durable .Overall, I am extremely satisfied with my purchase. however, the price may be a bit steep for some customers..

Pros
  • Perfect seal, improved performance, perfect fit, easy installation, high-quality materials, durable.
Cons
  • Higher price compared to other gaskets in the market.

They fit 8.1 liter big blocks

Although the description says they don't fit in 496 8.1 liter blocks. Yes, and I just installed it on a 2001 Sierra HD 2500. My exhaust leak is gone and they seal perfectly which my reflex seals didn't. BTW, you can reuse them, and the reflex I removed is complete garbage. Percy's is the way to go for everything and has been happy with all the different uses.

Pros
  • High marks for support and durability from testers
Cons
  • Poorly thought out
