Ls/vtec

Some time in the next 6 mounths I am planing on going LS/Vtec with my 93 teg ls...I was wondering how i can get higher rpm's out of this hybrid without hurting my engine. Also if anyone knows what type of cam shafts and cam gears would be the best for a b16a head on an ls block. Also i am not to sure on how stroke ratios work or if they can be changed, however i do know that 174 is the ideal stroke ratio and my ls block is 154 so if there is any way to raise my r/s ratio could someone please help me out with this.

-Also if anyone has any good sites or information about ls/vtec in general please let me know

Thanks,
Chris
