Engine heads are constructed of iron or aluminum.
On a 1995 Ford Explorer : The 4.0 liter V6 engine has a cast iron cylinder block and engine heads
I believe it is the process of removing material from the part of the heads that come into contact with the engine block. It is a way to make sure the connection between heads and block is flush. It will slightly increase your compression ratio depending on how much material is removed.
There are two cylinder heads on a V6 3.1L engine.

No, they are in the engine block, not in the heads. Freeze plugs are a misnomer. They are actually casting plugs.
305 heads work on a 350 engine
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.
Arden make crossflow heads for the a series engine.
the heads
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
No, the heads on a Ford 289 motor are not reversible. The cylinder heads are designed to be installed in a specific orientation to match the intake and exhaust ports on the engine block. Reversing the heads would result in misalignment of the ports and poor engine performance.
