Does anyone know what the little black metal tabs are that stick out at various points between different major 'blocks' on the motor? Like where the top end meets the lower part of the engine, it is like a gasket but metal. Well anyway, I probably sound like a complete idiot but when I put on my new header the bracket smashed one of those tabs. So basically the two are touching now. i've run it like that for over a month now with now issues but I know I did something wrong. Anyone run into this problem? Is it going to cause some problem? I know the header gets red hot and might be transferring heat to the cylinder.
