Header Leak??

One Word>>> REMFLEX no more issues. my headers (blackjack Alumicoat) are over 30 years old and until someone on here told me about the Remflex gaskets I was going to buy new headers, no matter what I tried, not needed with the remflex gaskets worth every penny...

I have to second this big time.
Remflex gaskets are soft and thick and compressable so sealing is a breeze.
They also gaurantee that they wont leak.
There is no need to run and then retighten.
They do not need sealer.

They are about 50 bucks a set and worth every friggin penny.
How much is 50 bucks compared to all the time people spend fighting leaks???
REMFLEX, Once and you are done.

There are VERY few products I will ever strongly recommend and Remflex is one.
The other is RainX so that ought to tell you something. :D
