When you do it clean both sides of the flanges, smear it on both sides of the gasket, give it 15 minutes, put it on, put on the headers and intake, snug everything but don't torque it down yet, then wait until the next morning to torque down the nuts on your studs. This will ensure a good seal.

I had a heck of a time getting mine to seal until I heeded the advice of my elders here and used the RTV.


I have never tried that! I did see someone using that on a car show I was watching. I think it was the spray on copper. I am not big on spray stuff though. I would rather smear it on by hand.
I am glad you added this. And I appreciate you explaining the way to use it. I would have put it on and just torqued it down.
I need to find the tightening sequence and torque for it. I will remember now to do it the way you described. Thank you!
