Default Power loss from 12-bolt

Anyone know right off the top.....about what loss of horsepower can I expect (as measured on the dyno) going from a 10-bolt to a 12-bolt?

Not to change the subject, but those are good dyno numbers you got there. What kind of heads are those? Do you happen to have an internet link for those heads? I have some budget stage 2 heads I'm not that happy with. I'm thinking about junking them and getting some better heads....
