Anyone ever run Speedmaster Heads on their small blocks

I'll be building a 360 for a friend of mine in the next couple of months, so I told him about the possibility SpeedMaster might have Black Firday-sale again soon... pretty much 2 SpeedMaster heads for the price of just 1 Eddy head....
But he's not a real patient person and had already ordered Edelbrocks instead already.
The name Edelbrock is still strong with people.
