  2. crappy heads?

    I bought These heads back in 05, before I knew as much as I do now. Will they support a 393 as is, or do I need to sell them, and get the next size up? http://www.summitracing.com/parts/TFS-51400002/

    Picture of the wrong. And the correct, for reference. I screwed the title up, why can't we edit titles? I guess I should learn to proofread before hitting submit.

  4. vacuum question

    I have an RPM Air Gap on my engine and it has two locations to draw a vacuum. One is directly under the carburetor and the other is in the runner going to the cylinder on the rear of the driver's side. Does it matter which location I tap into for my vacuum supply? Thanks. Dave
