Rule of thumb, the stock block starts getting iffy around 600 HP without extra effort like girdles and block fill. Low decks have their + and -. The shorter bores are stiffer which is a plus. On the minus side, a stroker needs a shorter rod, short piston (low compression height) or both.

With Eddy heads, you will be under 600 HP unless its a max effort, fully ported big cam build.

For what you are doing the RB should be fine. The longer rod/taller piston can help it last longer.
