Herbert SB Roller Lifters

Herbert Roller Lifters for a small block. Full set of 16 plus an extra pair with a bad wheel. I bought them used off of moparts, but in good shape other than cosmetic wear on the bodies. These are supposed to be drop-in or minimal effort roller lifters for a small block. 2 of the link bars just barely touched the lifter valley on my '72 340 block. Since it is an assembled engine, I'll go back to a flat tappet.
