Exhaust Crossover Restrictors

[82sbshortbed]

I'm installing the Edelbrock Performer EPS intake. The gaskets for it came with exhaust crossover Restrictors. It says not required but recommended for warmer climates. Don't get much warmer than Texas. So my question is has anyone ever used them because they live in warmer climate? The stock intake that I removed didn't have them. So was thinking not to use them.

If your manifold has the exhaust crossover passage, then it's up to you if you want the intake heated or not. If you don't drive in cold weather, it'd be best to leave it blocked.

If the manifold doesn't have a crossover, then you just leave the gaskets alone.

Unless you're going above 10,000 feet, I'd wouldn't use them and leave 'em blocked. Cooler intake mixture = more horsepower.

With propane fuel we block them off completely and run in the winter with no issues. I know you're not running pane but just wanted to throw this into the pile anyway.

I too would leave it blocked since you're in TX.

Thanks for the input . I'll just leave the gaskets alone and leave it blocked. Makes sense to keep intake cool as possible. Especially since it gets over 100 here in the summertime. The stock intake had the holes cut out of the gaskets (and no restrictor plates) using the exhaust crossover. It'll be interesting to see the difference in blocking it off. Thanks again.

I bought the same gasket, but I took some scrap I had laying around and cut a new peice using what they gave as a template. The reason being that their peice has a hole, so its not truly blocked off. Now the truck runs fine in 110 degree weather!

When I had my truck in Texas I used the block-off plate with the hole in it and it ran fine in hot weather. I'm now in the Washington DC area where temps get down into the teens in the winter, and it still runs fine.
