Can I use O-ringed heads w/ a non O-ringed block?

[satan jamez]

Will there be any mating issues. What gasket is capable of this?

I think you just run regular gaskets and the reciever o rings in the heads.

I ran a Fel Pro O ring gasket on the turbo setup and didnt have the block o ringed just the heads. I forget the number.
