Razor place, towel with rubbing alcohol or carb cleaner? Let me know going to head up to my friends house to install the heads and intake.

I use the gasket remover spray sold at the local NAPA store. It works great, especially on those hard to reach places like the waterpump-to-block gaskets.

I just use a razor blade, depending on where sometimes a wire wheel. I've used the Napa stuff before, works good, but don't get it on anything important, it melts stuff away.

I used one of these..

and one of these
http://www.google.com/products/catal...ed=0CGwQ8wIwAA

The first one I listed works great for gasket material that is so on there a razoer blade can't even get under it. Just angle it properly and give it a tap with the hammer and it will chunk it right off.

I have never tried gasket remover. Does it work really well for hard to reach places?

Gasket scraper or putty knife to get the big stuff off, and a wire wheel to really get the cast iron clean. Wipe down with lacquer thinner on a paper towel before putting on the new gasket.
