If you change to a roller, you'll have to change valve springs, distributor gear, lifters, pushrods, etc. It's not a quick and easy swap.
As for the valve cover flange, you will need to have your machinist mill the valve cover flange of the intake down to match the heads. Just take a measurement and correct it.

While I'm normally not one to quibble with your engine recommendations, if it were my car I'd be inclined to take the extra time, trouble and investment to convert to a roller (hydraulic if block drilled for it). The fact this is side-oiler in a Kirkham makes it even more appropriate, in my opinion.
Concur 100% on the intake machining - anything else is a less than optimal solution.
