Rat rodders don't give a fuck about going fast or taking turns. They also think primer is a color. They are the steampunkers of the hot rod universe - so long as it's made out of ostrich feathers and has surplus "e"s in the name, it's cool by default. I'm agnostic as to motors. My primary beef is affected primitiveness. Harley Evos? affected primitiveness. Pushrod V8s in the year 2016? affected primitiveness. For nearly any automotive application you care to name these days, there's probably a VVT DOHC sub-2L inline 4 that's doing the job quite nicely, thanks. But from an "art" standpoint? Fuckin' Ferrari 512 ain't bad. Too bad you can barely fit them on the road. For "real world" I gotta say there's something about the radial valve MV Agusta F4... ...but when I call an MV Agusta F4 "real world" you know I'm fucked in the head anyway.
Well, rat rods are more about aesthetics than functionality, which I'm sure you know but I'm just more stating this for anyone else who reads this. I do think though, there is something charming to the idea that they want to use flatheads for authenticity. They really aren't my thing, much like donks and lowriders aren't my thing, but when I see one at a show or out in the wild, in good shape and done well, I still find myself admiring them. They're all about form over function, but somehow function seems to find its way into their art. I think an extreme example, on the other end of the spectrum, would be pro-street and mudders, where function comes first, but somehow that function lends itself to a certain aesthetic that people try to emulate. My knowledge in automotive history is pretty spotty, but I think Honda could take a lot of credit for this trend. I'm not a Honda fanboy by any means, in fact Honda fanboys kind of turn me off to the brand if I'm being honest. But in the late '80s and early '90s, I think Honda's VTEC technology really paved the way for respecting smaller displacement engines. I'm unfamiliar with the engine so I googled it. Am I right in that it's for bikes? What do you like about it?Rat rodders don't give a fuck about going fast or taking turns. They also think primer is a color.

MV Agusta F4
That's just the thing: rat rods are all about functionality, same as rat bikes. You have this thing, you don't give a fuck what it looks like, you just drive it. That was my childhood. A rat rod used to be a Porsche 914 with a poorly-hidden Hillborn-injected V8 in the back. Hell, I know a guy who would build fast CVCCs by putting a motor/transaxle in the front and the back and then link up the shifters and throttles. Now it's this twee fuckin' fiberglass t-bucket with a lovingly-restored flathead v8 in it. Gimme a break. And yes - Honda pretty much made variable valve timing de rigeur. They came up with a way to do it pretty simply, so that's what everybody does. Makes a hell of a difference. The MV Agusta F4 engine is the only production multi-cylinder engine I know of with radial valve symmetry. Know the difference between a wedge combustion chamber and a hemi? Thing of it is, hemis aren't actually hemispherical - they're just tented. The MV actually has angle-cut cams because the valves are splayed out in two dimensions. It's actually a hemi.
