Gotta be careful when dislodging gunk. Yep, certainly scrape out what you can. But, as far as dislodging throughout the rest of the engine, can be a touchy situation because gunk can end up in oil passages, block them, and not good... Of course the best time to remove it is when is tore down, and then hot tank, but doesn't sound like you're doing that. Used to be a product on the market made just for that called Rislone, and maybe they still make it, but I've also rebuilt engines after Rislone was used, because it sure broke it loose, then blocked passages, and bearings ended up getting spun. I'm not saying or suggesting that Rislone's a bad product, because it sure does what it's supposed to do. The problem is that if its too gunked up, Rislone's going to dislodge it like is supposed to, and its going to end up somewhere, and spun bearings aint fun or cheap to deal with. Maybe pull the oil pan and see what it looks like up there. May not be so gunked up that couldn't try using a detergent oil as suggested.
I'm not going to tell you what to do, but whatever you decide on, be careful. Your money's not as easy to come by as it may've been not so long ago, and the last thing you need to do is have to invest it somewhere when that's not what you intended to do, at least not that way.
