Head Specs?

Does anyone happen to know the stock valve sizes (intake and exhaust) in a stock head from a 1989 302?
im trying to get a round about answer to how much horsepower my stang is running but i cant fill in the sizes because i cant find it anywhere, so if anyone knows or can give me somthing close to it, its much appreciated
