Yes. As long as it's close to the same displacement.
(350 heads won't work on a 283 etc.)

Re: stupid question

You can use just the intake by oleongating the bolt holes. If you want to use heads too they should bolt right up, and with no mods to the intake. Make sure of combustion chamber size, compression, and flow. Everything else is straight forward.

The only stupid question is the one not asked.
