Hi All,
I would be really cautious about having manifolds re-surfaced on a ram car. You have no margin for error with the angles in relation to the elbows and exhaust pipes. 
Anyone who has been in or around my G knows it's quiet. I run Fel-Pro gaskets on the exhaust manifolds, and Bob Merritt's reproductions on the elbows. They have been there since 2003. 
There is no real secret. The manifolds need to be initially torqued to 25 foot pounds. Start it and let it warm some without driving the car and re-torque it with it warm. Let it cool off over night and do it again. It's kind of a pain, but beats listening to exhaust leaks. All traces of old gasket must be removed before putting in the new one. I also cut out the gasket between the exhaust runners. It looks better, and may help too.

  Can we assume that there has been no warping of the block? Not much sense 
  in milling the manifolds if the surfaces to which they are to mate are not 
  true as well. I have a similar problem with my G and while I certainly 
  don't have headers on it, I keep blowing manifold gaskets one after the 
  other. Maybe I should consider having them milled to see what the result might 
  be.

  warped, most of them are ..bob hayen

  Hi,

  I remember some discussion about excessive heat coming out of the exhaust 
  ports and blowing header gaskets. Has this happened to you? Have you found 
  a relatively easy way to fix it? I REALLY don't want to remove the intakes 
  again. Is it possible to unfasten all the nuts and bolts and have enough 
  wiggle room to slip on a new gasket, or even to use a sealer or liquid 
  gasket? Is the temp. coming out of an exhaust port too much for a sealer? Didn't 
  someone say that some of these cars didn't even get header gaskets from the 
  factory?

  I hope someone can help answer this. The noise and fumes are getting 
  tiresome!

  Thanks,

  George Clineman
