Header Gasket

[Russell]

Update four years later.

Emery, you were right. My Mr. Gasket copper gasket failed after four years. I have replaced it with a Remflex as you mentioned four years ago. Lesson
learned the hard way.

Thanks again for the help.

Glad to hear you fixed your problem. I got a rod knock last June and the rebuilder finally finished the engine. I’ll pick it up Thursday. I have to order a new remflex gasket. Thanks for the reminder.

I have used the Remflex gaskets for the last 15 years. They make up for
uneven surfaces and I have never had one burn out.

Look as these 2 pictures;

and

Pay attention to the torque values. Do it in stages and they should NEVER
over torqued!! Always use new bolts and use the small hex headed bolts for
the headers and standard grade 5 (FIVE) for the manifolds. I would suggest
a high temp antiseize for the for all the threads.

The copper could be used also.

If you have iron manifolds and are willing to put up with the work, Dave Lenzi's copper gaskets are pretty good, but you need true manifolds and the
time to do the 5~7 retorques to make them work. I am hoping that they will keep the good manifolds from cracking. I do not have enough experience to
know that this will be true in the long term.

Hello John,You mention headers here.  I have to replace my leaky manifolds and have considered the headers, but have been told it will be louder and hotter in the cab?  What are the pros of the headers?Thanks,Eric
