No, you can swap lifters about as fast as an oil change..well one side.
Remove valve cover..the 5 bolts holding the rocker shaft down, remove rocker shaft and arms. Then get a magnet flexible rod and pull each lifter out by the big holes between the push rods.
I did mine during a cam swap and I had a lifter tray under the intake that needed to be pushed up while pulling each lifter.
Be sure to break in the lifters like you would a new cam...then again you might as well stick a new camshaft in once you get all the lifters out...
Guess wait until winter
