Burnt Spark Plug Boots

I was thinking about those but worried they will still burn. Would it be over kill to use the heat sleeves too?
Here's picture of the closeness of plug to headers and my steering rack. Is there a smaller steering rack that i can use in the car to get more clearance from the header? View attachment 1715423255 View attachment 1715423256View attachment 1715423257
