Hello, I have a lunati retro-fit roller cam and was wondering what size pushrods I needed? Is there a specific size or do I need to measure with one of the adjustable pushrods?

Yes,use a length checker.
Are you using adjustable rockers?
Hydraulic or solid?
What cam lift?
Do you know what your spring pressures are?
Can you fit 3/8 pushrods if needed?

And go talk to Mike at B3 so you can correct the rocker arm geometry. He knows of what he speaks.
Issue for me too.
Rockers with ball, should be adjusted where ball falls in line with shaft center and roller axis center for initial measurement.
Some folks just say “so many turns down”
This line should be perpendicular to the valve stem at/about mid lift. - adjusted by shaft height. Which may throw valve stem contact area off.
then measure.
Pushrods can be measured different ways. Make sure your supplier is clear on your measurement method before ordering.
