good day!

Haven't done it on a Kirkham, but on my own orig spec chassis.
I moved the driver footbox to the left, as well as the steering shaft to clear the head and notched the frame rails for starter/bellhousing clearance.
Yes, the steeing wheel (as well as column) is angled a bit, the dasboard cut a bit.

You could probably live without notching the frame, if you lift the engine. But now you battle to get hood clearance. (The steering shaft may clear the head)
With the supplied Victor Jr the hood was flush with the intake - without carb! (Crank CL 5" to 5 1/5" above frame rails)
If you raise the engine to clear the frame rails another inch...

I replaced the Victor with a Performer (The lowest you can get. Make sure it's for SCJ heads) and the CSX4000 hood scoop is now touching the lid of the (small) aircleaner.

No rubber mounts for the engine here, every millimeter counts.
Even the distributor cap is very close to the hood!

You may also battle to clear the 3/4x3/4" tubing running from front upper pedestal (upr control arm frame) to scuttle hoop with the headers. This is the frame to hold the steering mount before the first knuckle.
You don't want to remove that tube.

I am not doing it again! Next engine will be FE.

Oh, and consider the changes to be done to the engine for manual transmission. However, I believe FORD supplies a front sump version for Cobras now (460 only).
