Re: 258 valve cover
I've never seen a reason to switch from the stock cover. As long as the screws are tight it doesn't leak.
Next time yours startts to leak, take it off, remove the baffle and reinstall the cover. Then every morning, before you start the engine, tighten the hold down nuts. Dont overtighten them; just loosen the nut and then retighten it to the proper torque. At first you'll get a little extra out of them on the retighten, but eventually you'll find that they're turning right back to where they were. After that, just check them when you change oil, and you probably won't have any more leaks.
