Fuel Cell Foam or not

Hi all,
Looking to buy a fuel cell for my 87 Chevy truck. I've decided on the RCI 16 gallon fuel cell with sender but getting mixed feelings on, with or with out foam. The thing is its going to be driven at the track and once in a while on the street, I want to run NOS, but hear that the foam breaks down and can clog the nos ports, is this true? Do I really need the foam. Here are some of my specs.

383 stroker
AFR 220 racing heads
edelbrock rpm cam
Single plane intake
750 duel feed Holley
NOS, using plate style
Mallory electric fuel pump 140 w/Mallory paper fuel filter

Go with the foam, it keeps fuel slosh to a minimum. The foam takes a LONG time to break down with fuel, Alcohol breaks it down faster. I ran the same foam in my fuel cell for 7 years, it was still fine when I sold that car. I have a few buddies with race only cars and the foam in their cells is older than your average 4th grader.

Oh yeah and you are going to be running a filter between the cell and your pump anyway, so even if the foam breaks down your filter will catch it, long before it makes it to you nitrous jets or solenoid
