95 is probably a roller motor and the 82 is a flat tappet. long story short. you can use the 95 top end roller set up on the 82. but you have to use the entire valve train. cam, lifters, push rods, etc. also if useing the older block. you will need a hydraulic retro fit cam. as the block was originally a flat tappet block. the reason for the need of a retro fit cam is the cam cant be allowed to move forward or backwards in the engine. Flat-tappet cam lobes are ground at a very slight angle to prevent the cam from moving. Roller cams cannot be machined that way, so a roller-cam button is employed to limit cam movement. The spec is 0.003 to 0.005 inch. This is because load from the distributor drive gear. tries to push the camshaft rearward, which usually retards ignition timing. The button prevents this from occurring. hope this helps.
