    Question Head/block dowel pin alternative?

    So when I picked up my block from machine shop almost a month ago I didn't notice those guys took the dowels out.

    I realized it today when I put the head on, glad I didn't have the proper socket for ARP studs or I would have tightened it before noticing. I'm assuming ARP studs are not tight enough of a fit to go forward without the dowels.

    I doubt that shop will still have them this long after the job or even remember anything about them. Short of ordering new dowels, and waiting a week or more, is there something else that can be used in their place from a local hardware store? It's a long shot that they would have something exactly 8mm in diameter but maybe someone ran into this before.

    I would try a 8mm shouldered bolt , cut the threads off and then make the dowel out of the shoulder. Just make sure it's not to long to bottom out in the hole.

    Ah yes was just in the garage measuring stuff and ran into those. A little Dremel work, 8.04mm, and it should work.

    Well that was easy, cut the bolt head off, put it in my drill press and with a large file got it down to perfect fit.

    Good as new.
