Ok here are the pics
I will say the simplest way would be to put the strip between 2 aluminum 2” wide strips bend them round and put over cooling fins to heat engine. I enclosed mine and insulated it to heat engine faster. The main thing is to get the strip from link and use your imagination to make it work.

This strip will over heat engine so watch out, you can guess how I know this.
Heats my 21 go engine from 70 to starting of 200 in about 10 min.
Also heat strip has sticky back on one side.
