EQ Heads and stock rocker arms?

I am in process of tearing down a 5.9L magnum and hoping to rebuild for around 400hp carbed with an air gap intake, V belts, LA front cover, hughes cam, EQ heads and some dougs headers.

My question is pertaining to the rocker arms. In speaking with the guys from hughes they had mentioned I will need the HUG 1550 stainless rocker arms (Hughes Engines). Is there any reason I couldn't just use the rocker arms from the stock heads and save myself $345?

The cam I am thinking of using is this one: Hughes Engines

The EQ heads are these (with 1110 springs): Hughes Engines
