 Actually, I think just about any of the later Esprit heads are larger. I remember getting my 907 head off and looking at the ports - tiny! So, I bought later model instake gaskets for the Esprit and port matched them on the intake and exhaust side - 10 hours later I had a nice looking head with some big ports.

I think the best thing would be the big valve Lotus head, called the Zeus head, which is now the only thing that JAE offers for head replacement. It had, if I recall correctly, 1mm oversied intake valves when compared to a Lotus Esprit SE head, but, I don't know how a Lotus Esprit SE head compares to a 907 head except I know the ports are larger.
