Spark plugs

Will AutoLite #25 plugs that were bought to go in a '94 5.0 work in a '78 351M that has Autolite #26 plugs in it now?

They look the same. This 351 has been sitting a while. Oil pump locked up. I replaced the pump and I've bout got it ready to fire up, and have the #25 plugs on hand.

Like Jason said, 25's will work, they are just a colder plug. I'm actually running 24's in my 400, but I'm also running full MSD ignition.
