Can some one tell me about the GTP stage 3 heads, iv tried to find info about them on the internet but with no luck, i just got a set of these heads from a guy i go to school with they need minor repair, are they good heads?

 

Anyone??

 

Can you clarify what we're talking about? To me gtp heads means iron sixxer heads with injector bosses in them, but your sig says you've got an SS, obviously not a six.

 

as far as i know thay are a company that ports heads, the heads i got are a 241 casting head i just forund the name (Gallant Technical Performance)
