Timing issue 360 LA

Degree the cam. It sounds to me like it’s one of those deals where the crank gear has two dots and it’s timed with the keyway facing up. Pic stolen from the web.

I was 99% sure we did the cam gear timing correct. But it is possible. I have never run into an issue like this so it must be something out of the ordinary. Now is there a way I can check this without removing the engine and tearing it down again. I have no issues doing it if I know its wrong, but to spend the time, and money on new gaskets to do it and its correct would suck Thx
