I just recently purchased my cobra sometime around sept. and been trying to figure out why its overheating. I came to a understanding that i need to rebuild the head. So i decided that i have to tear the head off i should build the short-block. I talked to my brother talked to chicane, but did not really help (sorry i'm not some one to throw dirt on someone's name) lets just say it didn't clear many things up. Then i talked to CHP and they priced their pro-street kit (short block assembled) ran 3799. In the future i will go with forced introduction. (Most likely twin turbo) Just wanted to get some feed back on my situation, and i'm oped to suggestions and different options. I do live by torrence CA, so its somewhat convenient for me.
