WHY?

use on both sides. I use Edelbrock gasgacinch sealer.
I will try it, but i did use sealant on both sides of the tray so not sure why it didnt seal any imperfections..Like i said, the original intake didnt have ANYTHING but the valley tray..no gaskets or sealant or anything..I hope the gaskets fix this, i was really looking forward to the new intake.
