little valvetrain help please

Ok so this is my first engine build and I'm learning this as I go, That being said I fired it up my 360 today for the first time and it sounds pretty darn good and didn't explode. But there is a little noise coming from the valvetrain on one side.
I removed the valve covers and just cecked with my hand and it seemed that 2 of the rockers were a little wobbly and must be the cause.
I just used the old hydraulic pushrods out of the old block and old rocker arms and think this might be the problem, between decking and a different head gasket the distance must be different.
What is the best way to go about adjusting this, new adjustable pushrods or something else. Or am I way off track :scratch:
