Ford owned a controlling share of Mazda during the L series design, it was developed together by ford and Mazda. It’s not just the heads, everything is different except the cylinder blocks lineage. No interchangeable parts.
Also I was talking post COVID cars, since that’s what time we’re in. 2020+ American cars are not as good as they used to be.
Sure Ford co developed the engine, and it wasn’t put in American Ford models outside of the focus until 5 years after it’s development. But a lot of the research and design was mazda
The 2.3 block you have was based off the Mazda L engine that they had in the older rangers/b2000, but newer heads
The Ecoboost wouldn’t be good without Mazda and Cosworth
