cam swap

After some of the comments on previous posts i'm almost afraid to ask this question. Besides the obvious loss of lift, what are the effects of using a cam that was ground for a 1.7 (both in. and ex.) rocker on a set of 1.6 in and 1.5 ex rocker? Can the cam be used? It is brand new and has 840 in and 824 ex with 1.7. The duration at .050 is 285in and 294 ex. At .020 it is 318 and 332. The valve timing at .050 is 28 btdc in. and closes at 76 abdc. The ex is 81 bbdc and 33 atdc. The lobe seperation is 114. Thanks Mike
