I was just wondering if there were any professional-tier speed shops in the Bay Area that also do valve cover polishing on the side. My dad exchanged his old D16 valve cover and some cash for a polished one back in the 90s (can't remember if this was in the Peninsula or East Bay) but either way that place is long gone. Anyone here know of a place that does that sort of thing? I already tried to do it myself on a valve cover I got at the junkyard and it didn't come out too well, so 'd rather have a professional do it. Thanks in advance.
