Yes...the 5L Coyote is a dual overhead cam design that was debuted in 2011. Probably not what you are asking about.
I would like to see a photo of that one. I was not aware Ford ever produced a 385 series dual overhead cam engine. The FE series did have the very limited production 427 single overhead cam (SOHC) back in the 1960s.

When saying "they", is that referring to Ford? I do know that someone made 4 valve heads for the small block, but I've never heard of over head cam heads for the small block. I wouldn't be surprised if someone tried it and made some prototype heads at some time. There are always hot rodders coming up with wild ideas and trying them out. After all, that is what hot rodding is all about.

You asked a question.
A little research shows answers.
Early 60s Ford made an aluminum engine with OHC for INDY.

I'm not saying you're wrong, or that it didn't exist, I've just never heard of one. Not that I've heard of everything that ever existed, ever.

So with a little googling, there *was* a Race-Only DOHC engine that Holman-Moody developed in conjunction with Ford, apparently, that used the 385 Series bore spacing. But it never was put in any Production Cars for Homologation, and they only built 10 of them, according to everythig I've seen with a quick websearch.
Supposedly this is a picture of one, sitting on an engine stand.

Coats was working on a 32 valve spherical rotary valve head setup that was tested on a 5.0 windsor supposedly. No videos or pictures that i can find, but the one article i found said the heads alone on a 5.0 with stock short block made 470ish hp and could rev to 14k.... so thats magical i guess.

I worked at Indy in 1968 (for Valvoline) and Dan Gurney's team ran the OHC Ford engine in one car and an OHV Ford in another car. IIRC, his team finished 3rd and 4th that year. The OHC engine car finished 3rd, and the OHV engine car finished 4th. The truly amazing thing is the OHV car ran the 500 miles on a 15% Nitro mix. I know for sure because I mixed the fuel. I was sworn to secrecy until the race was over.

The 429 engine developed for NASCAR use was the Boss 429 on the street but it was not OHC.
The OHC engine used in Indy was a Windsor, but it wasn't a 302. It was based on the original Windsor engine used in the Fairlane and I believe it was 221 CID.

I don't remember the size on the OHC Indy Ford engine, but I remember that the OHV Ford engine that Gurney used was a 302. At that time, Indy car engines had displacement limits based on engine type and OHV was 5 Liter. One owner tried to qualify a Chevrolet OHV 302. His attempt to qualify was on 50% nitro but his engine couldn't stand the strain. He never did qualify. Gurney had to have one terrific engine builder for his 302 OHV to run 500 miles flat out on 15% nitro.

The 427 Tunnel Port was a pushrod motor. It just had mahoosively large ports, and they had to run a tube right through the center of the intake ports, to run the pushrods through. Hence "Tunnel Port" as they literally had a tunnel running through them.
