Edelbrock heads: Adjustable rockers needed?

So guys, I bit the bullet and bought a set of Eddy's 60779, for my '72 360 (bored to 378). I have KB notched pistons, MP cam, Hydraulic lifters and stamped steel rocker arms and otherwise pretty stock. Edelbrock instructions say I need to use adjustable rocker arms with these heads, but someone told me that hydraulic lifters act in place of adjusters. Is that correct or nuts? Will my setup work or do I need to go get adjustable rockers?
