Alright thanks guys. I am planning on taking the heads off of the engine to see what everything looks like just to make sure I do not have to rebuild it before I start buying replacement stuff. The engine was not running great when it was in the parts truck, and I am not sure what was going on with it.

How loose should the timing chain be? Mine has about a 1/2 inch of play in it. I have been thinking about just replacing it now so that I wont have to replace it later, but I was just wondering if there is to much play in it or not.

I also noticed some weird things on the exhaust manifold, They are only on one side of the engine, and they are a long skinny tube that just sticks into the exhaust port. Does anyone know what these do?
