It's not like lots of grinds don't exist already. There are a plethora of grinds, but as I, like many others, have experienced first hand that these grinds don't necessarily offer what one might expect. On my old JH, I used a profile from Camonics in Los Angeles (other parts suppliers out there are using these guys) and their 107-like cam falls short. It just doesn't have the same torque and lift combination that original 107 or 104's for that matter have. There's a club member down the street from me that runs 104 cams and he claims they are perfectly driveable around town. He runs high compression pistons and a big valve head and that's really what 104's want to get the most out of them.
Otherwise, a 104 inlet and 107 exhaust combination is supposed to be a great match in the Lotus 907 head. Garry Kemp described this to me once as more dynamic flow through the head (from the lift ratios) with a result that you end up with a bit more torque without costing you any top end power.
