power building heads

[thejman]

eddie has a good question i was told that the"p"s were better than regular 40s and that the only problems were with the headers. if anyone knows where i can get "p" specific headers please let me know cause my gt40ps will done being machined by tuesday. my father helps build engines for hamner racing engines in alabam and we are really porting the crap out of these heads and expect to see great results
