A friend bought INDY heads for his stroker this spring....soon as he fired it up, hydraulic a cylinder. A port had a pin hole letting water into the cylinder..... later was told 1 out of 20 heads is a leaker?
So, that was April or so....he is still waiting for a fix/ replacement/ or? wow cash like that and nada.
So, I bought his 440 source heads...he ran them for a year, now I run them...no problems.....all this despite what has been said about both head companies. It true...every one can have an issue, what's in a name anyway? Just say'in :)
