      Wouldn’t you know it?  I’m reading my downloaded manual to get the torque specs for my cylinder head bolts, and it refers me to Appendix A-3.  I scroll down, and lo and behold, it skipped from A-2 to A-4.  I’ve written to the website I bought the manual from but there’s been no reply yet.  Does anybody have this info that they could share with me?  Also, I am an auto mechanic with car engine rebuilding experience, and there is always a pattern, i.e. 1 thru 10 for example, and you torque them down in three steps.  I didn’t see that mentioned in the manual, either, or is that not a thing.  In the absence of guidance, I guess I’d start from the inside- between the cylinders- and work my way out.  Lastly, what a booger, as my shop teacher used to say!  Out of the ten bolts, 9 snapped off, and that was after trying heat, cold, penetrating oil, and careful impact wrench use.  Then of course one of the screws drilled out a bit off center, so I had to install a helicoil in that hole.  Thanks in advance for your help, again, guys
