300 I6 intake leaking

big78 4x4

Hi, I have a 78' F-250 4x4 whith the I6. It has headers and an offy DP 4 bbl alluminum intake with an edelbrock carb on it. This ran amazing for a while but the intake keeps leaking. Right now it has the Fel-pro gasket on it. I have heard that doubling up a Fel-Pro with copper spray works. any body tried that? any type of RTV work? I was plannin on fixing this friday or saturday and want to do it once and have it last. any ideas? thanks.

In my own world
mr gasket #260 is the gasket you need. coat it with the copper, and re-torque 3 times after it warms/ cools 3 times, and it should hold up for you

What Dusty said. Make sure you have a straight manifold first. If not, get new ones from LMC/ebay/NPD.
