If you are, as you say, new to wrenching, be aware that this is not just a wham bam thank you ma'am job. When you cut the heads off the bolts, you want to make SURE that the threads are dressed properly. You can do that by giving a slight bevel to the end where you cut the bolt head off with a bench grinder or file. Then, run a nut, starting from the other end of what is now a stud, all the way up, and OFF the end you just dressed. Do this until you can start the nut BY HAND on the end you just cut the head off before you attempt to either screw it into the engine, or use it to mount the plate. The engine is aluminum and the bolt has finer threads than what is normal for that size, so it is relatively easy to cross thread. Just be careful and you should be OK. And to answer your question about how to install the stud... just put two nuts on one end of the stud and tighten them to each other. Then take your wrench and use the nut on the end furthest away from the end you are screwing into the engine and screw it in until it stops. Then unlock the two nuts from each other and repeat for the other side. The order of installation once the studs are in place should be, motor mount (should be in place already), nut, plate, washer, nylock nut.
