1. What are the torque values for the two different length fasteners?

3. Is there a torque sequence ( tightening sequence and torque increments)?
TIA
The two different length screw’s you are talking about I believe are the ones for the valve cover, these should have the same torque on them. The short aluminum screws are torqued to a different setting. They say they should only be used once. Some people are replacing them with stainless steel screws, I would not do that myself but each to their own.
Aluminum and stainless steel are at opposite ends of the galvanic scale so will attack one another strongly in a moist atmosphere, like sea air especially.
I already have my aluminum screws ready on the shelf just in case I need them. 🤞
You should download the Service Manual from the ‘TSB and How To ‘ forum on this site, it has all your answers in it. It is in the ‘Documentation’ sticky.
