peak performance head on a stock viper


I'm sure it would add a few extra ponies up to 4hp maybe?...if your referring to the one on ebay I'd ask him...I'm waiting to hear back what kind've carbs setting would need to be done on a single pipe viper...I'm thinking you would hafta stagger the jetting...Plus an opticool gasket might also encourage cooling aswell...

cheers
