What kind of heads do i have?

you think? i wasn't so sure about it - i don't even know what's up with them. i've never taken the valve covers off - so i don't know if i've got stock rockers under there or what. the guy i bought it from was a complete n00b and i can't get in touch with the original owner of it - yeah, it's annoying, but what can you do?
 
But porting THESE heads would be MORE expensive than just buying the patriots.. plus, for 1000 to port with a valve job, i could just spend 200 more on some aluminums... i'd REALLY like to avoid spending all the money on these heads if i know i can get something better than what i've got for as cheap as possible.
