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

I totally agree, every detail is worth checking, being meticulous adds up will get you to the finish line faster than the next who isn't

Its for a buick grand national engine.but its still the same setup as the mopars with non adjustable rockers.i asked a few questions over at the buicks sites but it seems to be a ghost town over there,lol.

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.
