A little light, will likely float

Response to XE274 - will these springs work?

If they are installed at a factory 1.81 height on iron heads, seat pressure will be 112 and open is at best 250. That's plenty for a stocker, but if you are spinning it high enough to make some power for that cam, it'll likely float.

If you are using Edel heads at 1.88 installed height, they are way too weak.

Come back with what you are running for heads and a planned installed height as well as adjustable or stock rockers, but likely those springs aren't usable
