You're right... looking close it's the old stovebolt in both... silly actually as there's not a lot of difference from the 216 to the 235/261, certainly close enough that a skilled builder could make either represent the other. I don't know that you couldn't make a 230/250 or of either as well, only someone who really knew the engines could tell the difference with a different valve cover and a few relocations of accessories.

Found it in Resin, actually both the Stovebolt and the 194-250 http://earlyyearsresin.webs.com/
