Just curious if it's better to simply replace leaking, warped original valve covers with the newer "turbo" style or to fix the leaks by planing the gasket surface flat. I've read through the forums via the search function and it appears planing the originals can be done but I'm not sure if I'm really better off just buying the newer ones. I'd like to re-use my originals if surfacing them is a viable solution over buying new ones but don't want to waste time if the "real fix" is to just by the later style. Any thoughts from the experts on what's the better route? Thanks in advance,
