0.7 mm is quite a lot in terms of cam design, there is a chance that the stock springs could get coil bound and the dynamics could get a bit mental.
An good indication is to look at the cam durations if you can, if they are similar then kit springs would be a good idea, if the race cams are much longer duration you might get away with it.
