Hello everyone, Put my headers by Doug on tonight. Not too bad of an install on my 66 GTO . Does anyone have any feedback on the Bison header gaskets that come with Doug's headers. Any other recommendations? Thanks!

Gettin' ready to install Dougs Headers on my car as well. Did you use the supplied Bison gaskets? If so, did you also use sealer, and did they leak?

TO GTO70, Won't know if they leak or not until we fire up the new engine. We're about a month away from that, but I'll post the results. We did use a high temp silcone sealer......Gary

I tried getting some answers on this same topic last fall with no luck. The gaskets look to be top notch, but I ended up using the fel-pro header gaskets that come in the racing kit to be on the safe side. No leaks! I used the copper spray this time to, a lot less messier than silicone.
