I have a bad rocker on my 454 so I am going to order a new set. The current set is the stock 1.7 ratio. I see 1.8 ratio rockers available. What sort of gains can I expect to see with 1.8's.
Before going off on a tangent, make certain your valve springs can handle the increased squash and not bind. Also the increase spring pressures that will occur and the push rod openings as well. Because if you're at the limits presently, there could be catastrophe circumstances... JMHO!

Don't think it's much of a gain for a slow turning marine engine though..... (unless you put a supercharger on it.....then you want the highest lift you can get!)
