Check with your local dealer tomorrow...that would be the best bet. I know there are guys on here that know their stuff but I would still check the dealer.

I am nearly certain they are the same. Some 400's use an additional 2 plugs on side of block. Oil galley plugs are different on the later model blocks. Some use metric. Most freeze plug kits include the oil galley plugs also.

Yes they are all the same.

Best way to get them is as a "kit, consisting of all-brass ones for the water jackets.

Don't get them from the dealer. They won't even have brass ones (not freeze plugs anyway).

The brand most parts stores have the kits in is Pioneer.
