    Only took about 300 miles, but blew the drivers side header gasket yesterday. Going to forgo the gasket this time and try the copper rtv trick. Any tips on how to install so that it will last?

    I rough up of the head and the header flange a little bit with an emery cloth to give the RTV something to bite into. I let it dry at least 24 hours before use.

    Yeah I barely ever use a header gasket on a high boost or high compression car. Use Permatex Copper.

    thanks Rick! Do you let the Permatex skin over first then apply and fully tighten?

    Exactly the same here, Copper RTV and done. I have used the new Proform header bolts and they have been sweet!

    Are those the new wedge lock bolts? Happen to have the correct part number for these for Edelbrock heads on a sbf?

    For the aluminum heads they recommend the 1" long bolts, that is what I run in mine. I don't see a part number for the 1" long in a pack of 16 (damn chevy guys get catered to I swear...) I'll call Booth over at Proform today and see if they have a part number for us ford guys. I know they didn't when they first gave them to me to try but hopefully they stepped up the ford love

    Problem is most aftermarket alum heads will not accept a 1" long (stock length) bolt and require the 3/4" length...

    Switch to studs.

    As mentioned before, I rough up both surfaces. I put a small coat on both the head and manifold, then tighten just hand tight until it begins to squish out the sides. I wait a half hour or so until it's no longer tacky to the touch and then torque to spec.

    ordered some of those Proform bolts. They say torque to 28lbs, is this correct for aluminum heads?
