Lookin for L98 engine info

[thirdtimevetteowner]

Does anyone know if '89 L98 engines are equiped with roller cams? If so, can someone tell me the duration @.50 and lift specs, the LSA, and also if it has roller-tip rockers and are they 1.5 or 1.6 ratio? I would like to know this info to help decide on upgrades. I'm 56, but unfortunately "the need for speed" hasn't waned with age. Thanks to all who read this.
