Wondering if these Alum TP heads have been produced as of yet or an idea of when they might be available ? You can put me down for 4 sets of heads, 2 stock version and 2 max effort versions.
Ford offered a tunnel port package for the Windsor in the 90s.Required a unique block.Then they abruptly pulled it from the market and bought back parts that they had delivered.Why the special block, and what other development work was done for that package?
I wonder why they wanted them back so bad.
Jim was game to do about anything. The Ford guys told me that the idea of reshaping the PR tube, using various protrusions in the runners and other such ideas had produced absolutely nothing of benefit---ON THE INTAKE side. I was advised to pay attention to the exhaust.The end result was a set of Dove TP heads with the FoMoCo intake lay-out and Dove's 'Type Two' exhaust runners. The exhaust side was changed so radically that the head lost most of the FE identifying characteristics. The runners were raised, spread further apart, and reshaped.Jim's design had the angle of the exhaust runner re-done to such an extent that the runner opening was markedly 'up', almost pointing at the edge of the hood when bolted to a block in the car. The exhaust port shape had one lower corner filled-in quite significantly.KS

Midway through their release schedule they decided to pull the project. Then requested the return of parts they had shipped.Always wondered what the backstory was....

The head used "paired" exhaust valves ( #2 and 3 being next to each other ) with the 10 ( only) head bolts caused head gasket failures. Yes Jay Cushman bought out the left over JR Johnson stuff and there are other heads . blocks out there as well. Cams have an odd lobe layout for the alternative valve locations. After initial approval , Nascar didn't accept the engine combination . Randy

The exhaust has been significantly worked over and would require a custom made set of headers because the exhaust runners are directly in-line with the exhaust valves. Probably as straight of shot as you can make with the exhaust.
