I am going too install new roller rockers and I,m looking at the 1.85's but can I use them with my cam the specs are
224/232 581/593 Or would I be better off with the stock 1.7's? I already have stage 2 heads so springs shouldn't be a issue right?

You will not be able to use that cam with 1.85 rockers. The lift would be .632" and .645" Your springs will not handle this(unless you have a VERY unusual stage 2 head spring package).. also, it will put a very heavy load on your rollers, likely causing float, or loss of performance at higher rpms (even if the springs were up to the challenge). You'll have to swap in a milder cam if you want to use 1.85 rockers. I hope this helps.
