Posted October 11, 200915 yr comment_297263 Is there any way to distinguish between stock and turbo head bolts in the absence of numbered bags? I think they are stock but am not positive,also is there any harm in torqueing them to turbo specs just to be sure?Thanks,H Houghton Link to comment https://www.classiczcars.com/forums/topic/33500-identifying-head-bolts/ Share on other sites More sharing options...
October 12, 200915 yr comment_297277 I have a set of new turbo bolts in the nissan packing. They have a very small '13' marking on the top outside edge of the bolt. I can't find my stock bolts, but as I recall they were plain on top.Phred Link to comment https://www.classiczcars.com/forums/topic/33500-identifying-head-bolts/#findComment-297277 Share on other sites More sharing options...
