Removing spark plugs from a body

Not a problem hope it help. When I Frist drilled that hole I was runing a 906 headed 440 with the 2 inch TTI headers. I was off on the hole I think about a half inch. Because when I installed the Indy EZ heads with the angled spark plugs and the same headers the hole worked perfect. With the 906 heads It worked great useing a 3/8 extsion with wobble end. You got any pics of your car ?
