Anyone tried GTP heads? I have experience with their heads and I have talked to Craig over there, he seems to know his ****. Gustin uses his heads. Not sure on prices though.

 

i'm thinking of buying a set of the TEA 2.75 heads with the "special" nitrous exhaust port....they are VERY expensive though.

 

Gtp?????
