I received the following e-mail with comments and suggestions from Paul Kainth just a few days ago. Note that he says he used the same studs/torx screws and fit the plate over them. I did try that initially but could not figure out a way to get the nuts on to tighten them. Leaving them on would simplify the process a bit, but I remain skeptical that it will work and allow you to tighten the plate on properly.

Let me start by saying thank you for the instructions.
Just on the weekend I install a heater in my 2007 Toyota Highlander and and boy did your instruction make the job easy.
Before I started doing the job and went and talked to Toyota mechanic, he warned me head of time not to try removing the studs with Star head.
I did not use the ramps because I did not need / have to remove the engine cover on the bottom. I installed the block heater from the top by removing the metal plate on the exhaust manifold. Yes you are right removing the plate on the engine was a pain. As for the block heater fits fine on the engine studs and just reuse the nuts making the job less time consuming. It took me about 1.5 hours to do the entire job.
The reason why I'm send you this is maybe you can update your documents to let other know that it is possible to do the job without removing the engine cover and the studs.
