advice on heads w/ p-51 swap

i'm getting the p-51 intake, and i have no idea as to what heads i should go with...seeing as how i'm going with a fox lake intake, i thought maybe i should go with fox lake heads...but i have no idea....so anyone thats done the p-51 swap, help me out. oh btw, this is a daily driver and will cont. to be so street cams are going to be used as well ( i want to keep this thing as reliable as possible)<----if that helps any???
 
I have been looking at the fox lake heads as well...Do they modify the combustion chamber? eg. will these heads on a stock '03 GT block drop the compression? also if using an aftermarket cam with stock lift (.550) valve projection shouldn't be a problem should it? even if the duration is longer than stock?
