Getting desperate for guidance

I am ready to assemble the heads on my freshly machined 360. I have been searching for weeks for some basic instructions. The thing is most of the info I find says to install head gaskets dry. I will be installing Fel Pro gaskets and the instructions tell me to apply sealant to the metal side contacting the block. However I cannot find any sealant recommended for head gaskets or gasoline. Any Comments would be appreciated. Thanx

That's what I'll do. Q. on both sides, metal and fibre?

Thanks for the responses.

Interesting gasket and I can't say I've ever seen one like that. Copper spray on metal-to-metal works well. What's on the other side (I'm guessing gasket-to-head contact)? Can you snap a pic of both sides?

Yep, unless they specify something else, I'd say copper spray on the bottom and dry on the top. Don't forget to seal the threads of any head bolts that hit water with high-temp RTV.

I used to make extra money in college rebuilding Mercedes diesels 30 years ago. Think of them as having your head gasket problems x10.

We had a few come back with blown head gaskets until we started using the Permatex copper spray. Then that problem just stopped.
