Re: steel shim head gaskets for 400sb?

I bought cometic head gasket based on what you are doing they can make what ever you want. Now on that note I did have an oil leak on my engine. I had to use some sealent around the oil return area of the block head. I did not copper coat the MLS gasket as it states not to.Many have not done anything to the gasket and had no issues. Just my luck. SO if you decide to use them give Jason a call at cometic, he is very good to deal with.

BTW my MLS H/G was .040 and they will offer it how you want it. Custom bore size, thickness etc.
