That only works when both surfaces are straight and parallel to each other, you luck dog!grinning smiley

bite the bullet and buy permatex"right stuff". use no gasket. no problems. the only one you might is when you go to take it off again. did this to my tranny pan, had to use a pry bar to get off!!! stuff works.(aint cheap)

Great news!! Normally you can straighten...but a used stocker should be cheap!

I'm going to assume you meant "not warped" here based on the rest of the sentence.
You also said that you tightened it as tight as you could with a screwdriver.
So I'll further assume you have the original screw retention style that you are working with.
Chevrolet changed the system to a much improved spreader bar attached at the same points and used a longer bolt to retain this setup. It gives a far larger surface area of the gasket surface under compression and solves the leak problem oftentimes.
Others here referred to this, but here's an illustration:

The sheetmetal cover will usually compensate for some of that problem, especially with the improved hold down spreaders.
Does your setup look like the right side of my photo?

You can reshape the aluminum on the head that contacts the gasket with a long mill file to get a flatter surface...

Is the warpage a depression or a high area?

What is the amount?

25 thousandths?

On the bottom sealing area? in the middle? add putty!

At .025 I'd be surprised if these gaskets with spreader bars didn't seal it up.
