The plastic that the heater box is made from is some kind of styrene and responds well to heat. All I did to make clearance for the valve cover was to mark the area that needed to clear, heat it up with my heat gun and push it back. It took literally 3 minutes.
The box is fairly thin material and I think a good blowdryer would have done it if necessary. I used an oil filter as the item of choice as the "push-former" and it made a nicely rounded dent that is perfectly sized to clear even my tall race valve cover on my 302. It would also have no problem clearing with a 351W with normal covers.
