ok which ones are actualy worth a ****? i have an edelbrock intake so the stock covers wont work/seal. i took some chrome ones from auto at school (they were int eh trash why not? ) these are leaking too. My motor leaks on teh pass side, swapped covers and it stopped for about a week. Now it leaks again. my only thought is that the crhome is slipping on the gaskets and not sealing good. anyway which ones is everybody using?
