Hi. I'm no professional and fairly new to modding Evo's, but I'd say they are quite mild. Gsc s1's are 272/272 if im not mistaken, and I've just bought some s2's which are 274/274 which aren't overly aggressive as far as I know. I guess I'll find out for sure when I get the back next weekend tho. Once again, I'm no professional, but new springs are recommended on my 274's but not essential, so I'd assume the standard springs would be ok on your setup but I'm nowhere near positive. Sorry I can't give you a more straight answer but seeing as no one else has replied I thought I'd share my limited knowledge. I hope that's some help

I have been told that the lift is to high so I need to have the springs still not sure tho if I can use standard springs

Getting the springs would definitely be a good idea either way because the cams you're putting in are more aggressive than standard and as the springs get old and tired there's more chance of getting valve float. If you can afford it I would get them
