Question about valve cover fitment 440 in a Dart...

I was building my 70 Dart with a 383 and we had trouble fitting the Mopar Performance valve covers with the heater box in there, so we ended up painting some smaller 60's style valve covers and using those...

My Dad is putting a 440 in his 70 Dart and is wondering what valve covers you all use for a 440 build in a Dart considering this fitment issue we had before, and that he is using rollers and needs a bit more height than mine...

Anyone know???
