i just put a 6 liter in a 93 dually and I am almost ready to fire it up.... waiting on harness from Current Performance. But i have 2 questions...

On top of the intake there is a sender/sensor that has a hard plastic line from it... can i cap that off?

Also the steam line from each head i can attach it to the overflow right?

Thanks for all the help i will get some pictures up when i get it running
