Reply to "tappet bore bushings"

Frode,

Ford has not sold the bushing kit for decades. The current source is Wydendorf Machine.

I have no experience with CHI heads, so I'm not able to comment regarding the oil drain back holes. It will be easy enough to check this once you have the heads. Remember, not only is oil drain back important, but so is "ventilation".

I am ambivalent about the external oil drain back line. It won't hurt anything, but it most likely won't improve anything either. I don't promote it. I believe the tappet bore bushings will meter the amount of oil properly, making oil drain back less of an issue.

Happy New Year brother!

Your friend on the DTBB, George
