HTA Green, Built EJ205

Default Redline. Who says when?

I was informed that the EJ205 should not exceed 7800-8k with stock heads. Reason being shims tend to slide out from the bucket and cause major problems as well as stock oil pump cavitaing causing oiling issues with bearings. Makes sense. Now... I have built my motor with shimless buckets and have a 12mm pump. NO shims to come loose and have a larger wheel pump to stop the oil from being "beat up" and oxygenated. So... good to go now, right? 8k-8.5k shouldn't be an issue. Well... why not 9k-9.5k. What else will cause problems up there? My rotating assembly has been balanced to .25g's. I know the weight of it is also an issue. This I have done nothing with. I'm running an OTS Stage 4 crower cam, +1mm valves.. none of which is lightened (not to mention running a completely sotck crank). What is "safe." When is "when?" I'm trying to get the 205 into the 10.'s and have no choice but to run a monster snail so the extra rpm will only help.

So... spin it to 9 or be happy with the 8.5 line?

(for those that have followed my build... the Green is gone. Nothing smaller than 55lb/min will be in its place.
