If you need to know this i wouldn't suggest opening the engine to that extent. Grab a manual its like The Bible its surely to help you out completely.
Engine heads are constructed of iron or aluminum.
There are two cylinder heads on a V6 3.1L engine.
Sandwiched between the head/heads and the engine block.Sandwiched between the head/heads and the engine block.

305 heads work on a 350 engine
No, they are in the engine block, not in the heads. Freeze plugs are a misnomer. They are actually casting plugs.
The heads themselves have NO freeze plugs in them. But the block/engine has 8 freeze plugs in it.
Why 400 heads? They are notoriously bad flowing heads without much modification the engine would be about 360 cubic inches, but the heads have nothing to do with the size of the engine.
Just look on the block right above the transmission or right in front of the heads and then search that number through a book or the internet.
Heads off a 454 engine will not fit a 305 engine A 454 is a big block and a 305 is a small block. Even if they did fit it would probably run poorly due to low compression because the combustion chambers on the the 454 heads are larger than the ones on the 305 heads
Arden make crossflow heads for the a series engine.
