Question about ca compression

[Kaforlife]

I know my name says kaforlife but the CA bug bit me and after reading David's CA18DET Build-Up Thread I plan on doing the same. Question is if I was to bump up the compression to an 8.8:1 and do a 83.5 or 84mm bore would I have to anything else fuel wise tuning wise ect... I dont think I would but just to be on the safe side I thought I'll check(detonation sucks ) to make sure before I start buying everything. Also if the stock compression and bore (hence the box design) of the ca is something not to be messed and is perfect how it is just let me know and I'll just leave it the same. Oh yeah my long term HP goal is around 310-350 but thats in the far future I just dont want to have to open the engine again sorry for the long read ---

Thanks Ken
