You said 302.
One piece seal blocks are termed 5.0, since they have the new lightweight crankshaft balanced at 50 oz/in at the rear and 35 oz/in at the front.
One piece seal blocks can be flat tappet or roller tappet.
(Two piece seal cranks are 28/28 balance and heavier.)
To the best of my knowledge all assembly line 5.0 roller blocks are identical.
