Well, if you use Fel-Pro's with the stainless steel ring, they will sure-as-hell leave a nice indentation in your nice, soft, expensive aluminum heads that will need to be re-surfaced next time you have the heads off. You really don't want to do that. A much better choice would be to use Cometic multi-layer gaskets. You can even get them in whatever thickness you like to maintain your compression ratio instead of that super-thick Fel-Pro. Sure, they're expensive at around $90 apiece, but I only buy the best for my cars. My two cents.
