Putting a 426 Hemi in a 1966 Barracuda

I have a 440 in my 65 and haven't got to the brakes yet. Looks like the valve cover and master cylinder are going to be fighting over real estate. I can't imagine what a hemi fitting very well

I had a 440 in my 64 valiant. Just a standard chrome moroso valve cover. Cleared the master cyl and blower motor perfectly.
