Are Lighter 440 Pistons Worth the $$$ for the Street?

Howdy,

I'm planning on building a 440 for the street with some passes down the track here and there.

I can get the L2355F as part of a rebuild kit for $750 off Summit Racing, but I do realize they are heavy pistons.

If I go for Icon IC9953 pistons, I'll be spending around $550 for the lighter pistons alone.

Deducting all the other stuff from the rebuild kit, there's a couple of hundred dollars difference between the L2355F and the IC9953.

Is it really worth the money for a mostly street 440?

Thanks.
