2.02 or 1.90 intake valves?

For those of you that replied to my last forum on the Y heads, thanks!, But, I was misinformed. I did not win them so Im back to the drawing board. SOooo, As Im looking for another set of heads, Im not sure if I should look for ones with 1.90 or 2.02 intake valves. I got a 308 w/ the pistons notched for valve reliefs. (that sound right??) Itll have a b303 cam, cobra intake, and 410 gears. It is a STREET car but will see some 1/8 mile track time. Gimme your suggestions and any other info you need to help me out! Thanks!!! Chris
