db_buffer performance

I have an Oracle 9.2.0.4 database. I changed a few parameters and am not getting HORRIBLE db_buffer hit ratios.

Was:

db_block_buffers = 250000
db_block_size = 8192
db_cache_size = 70000000

is:
##db_block_buffers = 250000
db_block_size = 8192
db_cache_size = 80000000

I thought since going to 9i I didn't need db_block_buffers. Ideas?

Server is HP-UX 11i
Thanks!
