If you go with a .018 thinner headgasket could you still get away with the same pushrods on a hydraulic lifter engine?

DEPENDS , how much are the lifters already compressed from any head and/or block cutting that has already been done , assuming you have stock length pushrods.

Before you pull the rockers with the intake off see if you can see how much the lifters cups are preloaded.

usually you will not have a problem with a change like that. Hydraulic lifters have a lot of forgiveness built in. I would be very surprised if you were to have a problem.
