The flathead is good for compact size and nostalgia. That is about it.

Compactness, and some nostalgia, sure drive me toward the flathead layout. Even though I was born in early-90's I like some old stuff. But it still seems to be a sensible for some equipment which is either operated under severe inclination variations such as some lawn and garden equipment, aircraft, and eventually agricultural machinery when the usage of gaseous fuels is viable.

It was just one of the reasons why it ran too hot. Cadillac V8 flatheads and many inline flatheads from other manufacturers were less prone to overheating than the Ford V8, and having the exhaust running adjacent to the intake instead of through the block was a reason for that. BTW that 12-cyl boxer flathead is awesome.

Unless it has tech like the Honda 4 stroke trimmer engines, a 2 stroker is best for severe inclines.

Sure, but with a 4-stroke it's easier to meet current emission regulations without having to resort to direct injection.

The White flat-12 was only offered for a few years. Lubrication problems or something.

When I was in college I had a 1959 Rambler American. The carburetor bolted directly to the flat head and the exhaust pipe was strapped to the side of the block.

It is kinda hard to justify any engine with more than 8 cylinders anyway. I'd rather look for an 8-cyl instead of a 10-cyl or 12-cyl in the same displacement range anytime.

Is there still some love for the good old flathead layout?

Well, I still love my old Norton Big 4.
633cc of side valve single fun.

It's not practical, it's not economical, it's not fast, but I still love it.

https://www.google.com/search?q=beast+of+Turin& has a 28-liter inline four. It ran at Goodwood this year, but I think it's OHV.

If I had a running flat 12, I'd want it mid-rear in a bobber truck.

Countless four stroke lawnmower engines have been destroyed by oil starvation on inclines. I don't think we'll see direct injection lawnmowers anytime soon.

Blame it on the splash lube.

Though direct injection wouldn't become available in lawnmowers so soon, it was the only way to keep 2-stroke engines competitive in emissions-regulated markets for other applications such as outboard motors.
