Distinction between 61 Low and High Horse engine

[M W.]

I am currently in the process of restoring my original 1961 245hp 2x4 setup. My question is in regards to the correct tachometer face which should be in my tachometer. Should the redline be at 5500 or 6500? I currently have my dash assembly out so to change the face would be childs play. Thanks so much.

5500 for both the 230 and 245. Same engine, different induction. The solid lifter engines had the 6500 redline.
