Is my engine performing as it should??

Thanks for the answers, I know the cam is kinda dinky, but at the time it was all about saving money, because with the bigger cam I would need new rockers arms, I think I read the max for those were like .475 lift or so. I've wanted to have a bigger cam now that I have more money, but how much HP should I gain from switching to something like a purple Cam "P4120231" and added a 1.7ratio rocker arm? It would give me .549 lift, but 'm not sure if that's too much ramp rate, and how would it act with only 9.3:1 compression? And one person recommended the Comp XE274H. How would it compare to the purple cam I'm looking at?

And I would like to have a lower gear, but it is a daily driver (I'm in highschool) and I drive down a highway everyday.

And I'm afraid i might of sounded a little on the cocky side with the numbers I mentioned, but I was not for sure what to say Because CompCam's "Camquest" showed 525hp??? Which did sound wayyy high to me, and Desktop Dyno showed like 460-480 from what I remember. I'm never trusting those again, because i'm pretty sure I gave them accurate data. I used flow numbers from another set of ported J heads. Which may or may not be accurate.
