Works here.
I cheated switched the 50 and the 60 mhz chips
then changed the multiplier on the 603 overclocked both and it didn't cost a dime.
60mhz 060 /275 mhz 603
had to change the memory timming on the 603 to no precharge.

BTW the memory timeing settings in the early boot settings will make more of a diference than overclocking

But I would glue a heat sink on the SCSI chip.

I did, and my machine was allot happier.
Actually I ripped off the phase5 heatsink and mounted fans and coolers all around. Anything that got hot got a heatsink glued on it. Added a pound to the blizzard card but it should last longer.

Been using it at work. so I haven't had a chance to do more damage to it. Planning on water cooling it one of these day's custom water block the works
