can the IC in this circuit be replace with the normal Quad 2 input Nand gate

I want  to make a inductance meter circuit but i cant access the I.C in the schematic because the electronics store near me that sells NTE parts, dont have it. I was wondering how much different will the circuit operate if i use a quad 2 input nand gate.

What are you proposing to use instead-  LS series ?
