YES, Unless someone has installed a solid lift cam sometime are another.

Most Chevy 350 4 bolt engines will bolt into a 1979 Corvette.

Not if you did it right the first time.
370 HP had the big heads (2.02 valves) and mechanical valve lifters, 300 and 350 had hydraulic valve lifters, but the 350 had the bigger heads.
It's not recommended to change just the lifters. The cam and lifters should be replaced together. To get at the lifters, you can remove the rocker covers and intake manifold, loosen the rockers enough to get the pushrods out, then pull out the lifters.
Not that difficult but the 350, 5.7Liter has hydraulic lifters and you must be sure the oil hole is lined up with oil hole in block
hydraulic-type lifters do not have tappet clearance. follow manufacturer's recommendation for lifter preload.
You could take off a rocker and try to push down on the pushrod. You'd be able to feel the spring in a hydraulic lifter, but not on a solid lifter.
