idc what anybody says about the 98's having crappy heads/ poorly flowing heads the stock 241s really dont make that much of a difference. im turning 11.80s with my internally stock crappy 98

98 was the first year for LS1 fbodies, usually want to stay away from the first year models. main reasons sometimes the connecting rod bolts were weak and could break, the clutch hydraulics werent too good for hig rpm shifts and hard launches thats really the only two bad things about them. solution- upgrade the slave cylinder and get ARP rod bolts and youre good to go.

the only difference i can think of other than the slightly better 241 heads and slightly smaller cam was that the 01-02 models came with a better slave cyl (which ive broken before) and a LS6 intake-which probably has more effect on performance than the 241 heads do. there were minor changes in the pollution crap too
