will there be any changes that i will have to make when switching from a stage two to stage 3? will i still have enough valve adjustment and will the stock springs survive? thanks for your feed back guys

No changes needed. Both drop in cams. Springs arent a bad thing to do on either but no..they are not required.
Been running an hc3 for years now on stock springs/head. No problems.
