Here's some morning motor-porn. Makes me think the G45 head could be adapted to do this modernly.

Curious how well it performed. Looks cool as heck tho

It was a virtual bolt on conversion to a 289 head. Because of that the performance was not significantly better. Certainly not enough to justify the cost , even in the day.I had an opportunity to buy that engine about 50 years ago and did allot of research on the power is made ( around 300 according to Ford Engineering) and passed on it because of that.

I would rather have the 32v pushrod heads...too bad the company only made a few sets before going under:

Makes me think the OHC would have worked best on a Boss302. Then you'd have the breathing that the engine needs, not limited by the small ports of the standard 289 head.

Looks like a nightmare to me. Just because Ford could doesn't mean they should.
Breathing can be addressed on a 289 without going to that extreme, stroke cannot.

I remember a decade or two ago reading about the Coates rotary valve heads. At the time, they flowed more air than any conventional head on the market. Neat design.

Another example of something that looks great on paper, but does't work in the real world.
Not able to do an OHC on a canted valve head even with a rocker actuated version.
Loser . I built a 331 with 13-1 and a solid roller using these heads with all titanium valves . Ran 11.70s at 118 mph. Switched to Vic Jr's , lost compression ( 11.5-1) and went 11oh's at 123 same short block/ car combination.

J Bittle begs to differ.....
I will tell you that 7K worth of Crower crank, rods and Ross pistons fixes a lot of 302 Tunnel Port issues.
Those heads do actually work, unlike most of the oddities. However you could build a full big inch boss 429 cheaper I think.
I think CHI heads are probably the best HP per dollar aftermarket heads.

Rolls Royce did this on an aircraft engine back in the 30's. There's one in the RAF museum in LondonI remember a decade or two ago reading about the Coates rotary valve heads. At the time, they flowed more air than any conventional head on the market. Neat design.
