best heads for emissions legal package Im going with either a tr220 or 02 ls6 cam in my 2001 Z28 M6. I want a set of heads that will match up well these cams. I might do longtubes with cats ( yes i know theyre not legal for the visual test) im mostly worried about the sniffer. I want something much stronger then stock, but still good for day to day driving. thanks
