The numbers you have are for valve opening and closing for intake and exhaust. They are worthless unless you know if they are at .050" or actual seat timing ( when the valve actually touches the head ). A lot of makers don't give out this information to hide there speed secrets. Its just like advertised cam spec's. ie... 308/320 ???? when or where are they measuring from? Who knows, its just a marketing scam to make there cam sound good.
You must have actual spec's to do what you want. Joe
