    The bolts originally installed back then probably were cadmium plated.  You won’t find cad plated bolts anymore.  In addition, OMC was notorious for using odd length bolts or odd thread lengths.  So, be careful when shopping at the hardware store.

    Advice from here is unless you have good reason not to, just reuse the old bolts.  They might be better than what you buy now.  And no, they are not torque yield.

    Listen to Frank, no need to replace those head bolts unless obviously damaged.  The head bolt torque is only 60-80inch pounds which won’t stress the bolts at all.
