Burnt Spark Plug Boots

Ceramic plug wires from Accel, never burn em’ again.

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? 20191114-steering rack and headers1.JPG 20191114-steering rack and headers2.JPG20191114-spark plug#5.JPG
