1969 Barracuda 340 Formula S Restoration

Don't think so. The rocker supports are in line with the pushrods. The rocker shaft would need to move closer to the intake side of the head.
I've got my machinist lined up to mill out the bottom of the holes for me. It is great that he lives just down the street from me and has a Bridgeport milling machine.
Hope you and your family have a safe and happy Easter.

Ya, makes sense, unless the shims offset the shafts they wouldn't work. Also would need adjustable pushrods.

You're so lucky to have a capable machinist that close. I bet he gets great Christmas gifts from you !! LOL.

Have a safe and happy Easter as well.

Looking forward to the progress.
