That is correct. Any given high performance cam is DESIGNED to run on a certain diameter lifter.
If a given cam is designed to run on a 1 inch lifter, going to a 1.1 inch lifter is NOT going to change anything except add unecessaary weight to the valve train.
Running a smaller diameter than specified lifter will quickly destroy the lifter and the lobe.
