Evolution - Evo (common) Blockhead (rare)
Twin Cam - Twinkie (common) Fathead (rare) Castlehead (rarer)

Personally, I think that "Twinkle" sucks.....

I'll look when I get home but it doesn't ring a bell. Of course by bell isn't what it once was.

The Ironhead is an older HD engine.

Yes, the Ironhead is a very popular engine for classic sporties and IIRC, was last built almost 30 years ago...
I have heard an EVO called a "Blockhead", never heard castlehead either.

As stated the riders/enthusiasts gave the various engines their names. Harley accepted and perpetuated them. Flathead, Knucklehead, Panhead and Shovelhead were called so because of their patricular head or valve cover design/appearance. The Evolution mo****r was a HD designator as is the Blockhead name. Evo and Twinkie are again rider/enthusiasts names given those engines. Ironhead is indeed a rider name for the early Sporty engines. I think Blockhead kinda went out of favor because of the negative use of the term. Revolution, I believe, is the name HD gave the liquid cooled Vrod engine.

Two huge ATTA-BOY's for the first five who can name the bike attached to the ashtray engine.
