im sure the p's are nice, but i got my (non p's) off a 97 exploder, the heads went into a machine shop for refreshing, and .010 mill, i then bought them for 450$ i put them right back in the shop for some porting and 3 angle, then i put new springs on, if i would have had to pay for that port work, i could have already bought some gt-40x  and been happier...but oh well
with the better springs i got 4-5 mph with the e-cam, explorer intake, and gt-40 heads, i think ported e7's can match these heads though.
I will say, if your going to just leave them stock, dont bother, but with porting they'll be good, i would rathe rhave ported e7's with some good springs, then some unported gt-40 irons...my .02
