Default Hood Scoops vs. Cowles.... For Vapor Lock Problem.

Hey there. I have a Vapor Lock problem in the engine compartment with my truck. I have done a few things. I try to keep the chasis clean to wrapping the gas lines with high temp tape they use on Nascars. It all seems to work, except on days it get up in the 90's or hotter.

I have been looking into Cowles, and hood scoops to get more airflow and reduce engine temps a little on hot days, and in between There is an arguement among many people though.

Some say Cowles are better with airflow coming in through grill, and out on top combined with through the chassis on bottom. Others say the rammed air from scoops are better forcing the hot air out.

I have been thinking, and though why not a hood scoop with louvers on the sides to get both?

Any suggestions, ideas? I need to get this done before summer...
