how to seal header gaskets

(1/1)

spookie:
Stahl pattern zoomie headers,milled flat.What is the best way to seal gasket.What is your gasket choice? INjected on alcohol.

JEFF/21C:
i've found that it more in the type of fasteners than the gasket that lessens the chance of leakage, and flange thickness and support also help

THE FRENCHTOWN FLYER:
No gaskets
Hi-Temp red RTV
metal-to-metal

wideopen231:
Not sure you can get them for your headers. I use copper gaskets on my Hemi stuff. I have used the copper gasket maker by Permatex. Tip make sure it isd good a dry before firing or it will cover the side of the trailer and PIA to get off.

spookie:
Thanks for all the help.I will try Permatex copper.
