    03 Cobra blew spark plug, need new heads!

    Well just driving to work the other morning, not even in boost or anything my motor decided to shoot a spark plug out of the #3 cylinder. I would post pics but im sure you all know what a smashed spark plug looks like

    Anyways before someone tells me to do a Helicoil/Timesert Ive already gone that route and it wouldnt thread in for whatever reason, not to mention the fact I have heard to stay away for a few reasons, something about heat transfer in the heads, and the fact the other 7 plugs could also blow out due to me having the 4 thread heads. I have little to no money and was wondering if anyone could help me out on where I can buy a set of revised heads (or comparable) so I dont have the car down for too long, any help would be appreciated. Or any suggestions on what I should do. It is my DD for now but am savign up for a cheap beater to DD so I dont have to worry about driving the Cobra every day and keepign wear/tear off her.

    My plan is do buy a set of new Revised 05 Nine thread heads and put in a set of Forged Manley pistons so I will have a near 1000 hp capable shortblock and need heads so all I need to do is throw boost at it.

    Anyone Know where I can get a set of good heads that wont break the bank??

    I don't know anything about your heads or what they are even made from, but what I do know is that when I have an object of a metallic kind that is messed up somehow, I take it to my local tool maker/machinist/welder in town and he unf#%ks it for me. It has been my experience that very little in the metallic world cannot be fixed by a competent toolmaker/machinist/welder.
