You *may* gain 4-7 hp compared to the 853 castings. Once ported it's all a moot point. If you're going through the trouble to swap heads you should be doing ported ones. Why gain almost nothing when you can buy some used ported ones and gain 35+ hp... and do a cam too... another 40+ hp???
Like chriswtx said- the springs are the same. You can't use them with anything more aggressive than the stock cam.

The difference in power between the two castings came from the 241's being cast in a semi-permanent mold compared to a sand casting. The 241's have smoother ports, and are more symetrical. There is a *maybe* 4-7 hp gain.
Regardless of casting, why would you do a head swap to put on another set of un-ported heads that you won't feel a difference with?
