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

Looks like a nightmare to me. Just because Ford could doesn't mean they should.Here's some morning motor-porn. Makes me think the G45 head could be adapted to do this modernly.

Not able to do an OHC on a canted valve head even with a rocker actuated version.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.

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.
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.
