As far as I know (cam card is at home) the F303 cam has 110 lobe seperation and 288 degrees duration. I run one in my car (see sig) and love it. The car idles low enough to get some pretty good lope out of it without stalling or hesitating and my car is very streetable. I went with it because a few people told me it's a good blower cam, and since I plan to add a blower sometime soon I went with it. Some people advised against the F cam with my setup, but I'd buy it again if I had to do it over. After I get more into my mods I do plan to go with a custom grind though. But for an off the shelf cam I do think it's a good choice for my setup.

As for the 1.72 rockers - I am using stock E7 heads that have been shaved .03 and with my 1.6 rockers piston to valve clearance on the intake side checked .095 with my stock pistons. It's close, but it works. I don't know how much different the valve height is with the GT-40 heads so I can't comment on whether the 1.72 rockers will work or not. I know they would cause some serious damage with my heads. No matter what cam you go with it would be a good idea to check the clearence anyway.
