Re: Permanent 300 Six Cyl Head CFM solutions- A Work in Progress

Gramps,

No, I don't have any blueprint dimensions of the Ford head casting. Sorry for the confusion.

My question is, how does the cylinder head deck thickness between the new U flow head castings you are working with compare to the 65-96 Ford castings?

Thank you,

Curious what the deck thickness is on the new U flow head? I assume you know what the Ford blueprint dimension is supposed to be. I can measure if need be.

I've read that the new castings are thicker but, haven't seen any numbers.

They start much, much better if there is 12 volts at the coil during cranking. If you don't already have one, add a wire from the crank position of your ignition switch / circuit to the output side of the ballast resistor. This will put 12 volts, (only during cranking) where you currently are showin...
