    Pretty sure the part # is 304Y

    No clearance problems at all with my BBC and it clears both the front shaft and shackles with room to spare. I've tried 3 other brands and they all had clearance problems on the shaft and shackles. Doug Thorley is a very nice header. The only I don't like is the 2.5" collector (they should of done 3") but if you plan on running dual 2.5" or single 3" exhaust then they'll work great.
