I found metal gaskets on my engine when I pulled off the intake manifold. I didn't quite expect that! What are the benefits of metal vs. composition?

I [u]always</u> use a good composition intake gasket. The metal gaskets were designed for new surfaces. The older this stuff gets, the less pristine the surface is. A good composition gasket is important.
I good gasket is made and sold by Myers Studebaker...

The metal gaskets are supposed to give you about a half point more compression. I've tried them, and they are very hard to get to seal properly. If you want to use them, I recommend planing the heads and decking the block to get flat surfaces - by the time you have done all that, you can probably get your compression with the composition gaskets anyway. The composition gaskets are much more forgiving, and easier to work with.

Wacker, I don't think you are reading Clark's post? He is NOT talking about Head Gaskets! It's a 259 intake.

Clark, the factory always used Victor beaded steel, and they work OK on most intakes, some soft ones burn through or warp because of the very hot center port. Other composition ones work very well. If a heat riser valve on right exhaust manifold is used (not as important in Calif.) it needs to be free, in good working order to prevent overheating the crossover port in the intake manifold.
