    Valve cover and camshaft bearing caps bolts.

    Hi,

    I will be soon be putting the cylinder head back on my GS650, and planning of replacing valve cover and camshaft bearing cap bolts. Thinking of going for A2 stainless steel for the valve cover, and HT grade 8,8 for the bearing caps, is this a good idea, or any better suggestions?

    Thanks

    The stock cam cap screws have a 9 grade on them which is similar to metric 10.9 or SAE Grade 8. The stockers are nice because they have a washer built into the head.

    The valve cover screw strength doesn't matter but I like the stockers best because they are hex head and have a built in washer. Lots of guys prefer stainless though so...

      If bearing cap bolts have a grade 9 on them, then I better go with metric 10.9. Here in the UK we refer to stockers as flange bolts, those are the ones I'm going for.

      Cheers
