The stock cams in a 103 were the SE253 or HD part # 25376-03.
Intake .530 lift 237 duration open 9 BTDC close 51 ABDC
Exhaust .530 lift 252 duration open 62 BBDC close 17 ATDC
Proper citation where it belongs; the lift and duration I remembered. The rest were stolen from a post of Shrader's from a long time ago.
