You need an engine from a RL..... I'd suggest you just trade your non-RL block for an RL vesion.....
Since you need the whole engine anyway, try to trade your block for discount on a used motor (complete).
If you're going to try to outfit a bare block & you don't have those other elements (heads, manifolds, etc.), you're going to get set back a whole lot of buckaroos.
You're asking for trouble by mixing & matching, unless you're expert on the variations & compatibility factors..... and if you were you wouldn't be asking here. There are precious few who can tell you every little compatibility nuance of various engine applications & years.
If you REALLY want to know if the block is the same (identical/interchangeable) as RL, then just check the parts list under Honda Parts on-line (Bernardiparts.com or similar). Look up the "source" vehicle for your block & look up the RL. If they are NOT the same P/N, then you need a new plan.... unless you're a real gambler with your time & money.
