Leaky and Ineffective Gasket

My analysis of this automotive gasket showed that it did not live up to its claims of ultra seal. Despite being marketed as a high-quality gasket, it failed to prevent leaks between the manifold and the engine block. The only pro I could think of is that it was easy to install. However, the cons outweighed this benefit as I had to replace it soon after installation. Overall, I do not recommend this gasket for anyone looking for a reliable and effective sealing solution.

Pros
  • Easy to use and apply.
Cons
  • May require frequent reapplication to maintain effectiveness over time.

Excellent exhaust manifold gaskets

These gaskets are perfect for my '69 Pontiac 350 engine with RAIII exhaust manifolds. The tightness is better than anything I've bought before. Would recommend and buy again if needed.

Pros
  • Recommended for OE replacement, high performance street racing, drag racing and oval track
Cons
  • Great price

77 Pontiac 400 good for parts

A Pontiac guru told me that exhaust manifold gaskets are a weak point. He wanted me to double those pads. I prefer not because IMO these pads are well made and very strong. But just in case I bought an extra set.

Pros
  • D-port gasket is 2.00 high and 1.55 wide
Cons
  • Definitely a bad product
