I am working long hours to finish my 51 GMC and I am currently adding components to the engine. Here is a shot of my engine:

I was wondering, number one, the best way to tap the harmonic balancer in a little more to make it line up, without damaging the pulley: [img]http://inlinethumb03.webshots.com/4354/2830472700100058208S425x425Q85.jpg[/img]

number two, what could be the problem with my manifold exhaust donut gasket? It fits in the bottom half, but the top half is not beveled like the bottom. I'm thinking that the old one might have hardened in the top???
