its not ALL about peak flow numbers........velocity makes a big difference when it comes to real power.


although there are also plent of occasions of people unhappy with GTP heads.

personally i think they are way overpriced to begin with, i dont see why anyone would buy them.

 

Sorry but those numbers suck, not just the peak numbers but the mid .300 lift numbers blow, my Lloyd Eliot (LE) LT1 heads flow 202.5 @ .300 compared to your 185 @ .300, mid lift is what really counts in my opinion since thats where your piston is sucking the hardest, 75% down the bore ussually depending on cam but around there.

I would contact Lloyd Elliot, his prices are awesome & well, just look at my numbers with no tunning
