    ............ah, thanks very much. Just what I needed. I had already downloaded the instructions, but "Googled" the ELECTRIC COMPRESSION RELEASE 90-4914 part and voila! I love this forum..

    Not sure but it would have to have the same thread pitch as the stock unit and you would not want it to protude any deeper than the stock unit. Also if you look at it, it is very short and would be very deep in the rocker box if it did fit. If you were to pull your heads they can be machined for C/R's right near the spark plug.

    No. The above C/R's are 10mm. We have 14mm holes for our C/R's. Im researching this also as Im looking to replace the electric C/R's with manuals. But I dont like the cable operated manuals from S&S.

    I found these a while ago and have been sitting on them wondering if they would fit our heads. I wonder if S&S has a special thread cut so we are restricted to just their products. I know S&S wouldnt tell me anything, so I havent asked. I heard we have 14mm bolt holes so I wonder if these might work. Anyone with more info would be greatly appreciated here.

    I think I would trust John Sach's as the engine builder to know what works.

    Franco,
    Check your pm.
    The S&S manual or electric releases are the only game in town.
