crower 403's with stock springs and retainers?

I just ordered the crower 403 cams and i was wondering if it would be ok with the stock springs and retainers as long as i dont rev higher than stock limits. Eventually i plan on getting the crower dual springs and titanium retainers, but until then will it be ok? is anyone running crowers on stock springs and retainers? if so could you tell me how the ride is, any problems?

Thanks

You can do it ,but I would not recommend it,besides you’re right there doing the work why do it twice.Wait a bit and do it all at once.

yeah i think i will, but what would happen if i didnt?
any major probs? oh and do you know a site with good prices for spring and retainers for the 403’s?
