No offense, but why do you think the P heads are crap? They flow better than the gt40's and have a better designed spark plug location.
small valves, small ports, redesigned plug hole makes you use a special header etc.
i just dont like them... i have YET to see anyone post ANY respectable numbers with them. i have however watched a stock cam stock internal car go mid 11's on gt40's from a '93 cobra plus a 125 shot on 4.10's. and that was it.....
yes i've seen the flow charts, but i always say i dont care about flow.
and thats just my opinion too..... i wouldnt use them if you gave them to me, same goes for the explorer intake... and i use a gt40 tubular so i am a fan of gt40 stuff
