4th Gen Egg moves

[Jedi-Dave]

Hi PokeFans, I'm new here and have a question about egg moves, specifically Marowak in Gen IV.
Is there a way that I can get both Double Kick and Iron Head on Marowak? I have pokemon that possess both moves but I don't know how to get both onto Marowak.

Sees no way to do so. Passes egg moves solely from the male parent in Generation 4.

Double Kick options: Nidoran (male) line and Treecko line
Iron Head options: Aron line, Shieldon line, Larvitar line, and Gible line

Contains no overlap. Renders the combination impossible.

(Should be correct, anyways. Is not super familiar with old egg mechanics. Glanced through information about the old ways.)
