head gasket replacement thread?

When you reinstall the head, replace the short coolant hose between the head and block, since that is hard to do later. I put silicone hose on mine (check ebay), with euro-style hose clamps that don't cut it.

Insure that you clean both surfaces perfectly, using a razor blade on any suspect spot. Most people get the head resurfaced when doing a valve job. The block surface is usually pretty straight, and only the heads warp (but not as easy as aluminum heads do).
