I picked up a Briggs Raptor last year and finally got around to working on it. Unfortunately, I had to switch to another engine when I noticed this:

Yeah, I don't think that crack is a good thing. Not sure if this is worth repairing, but was curious if you guys had any thoughts.

That doesn't look critical... yet... but know this; that the lifter gallery (the area in question),
is typically welded for reinforcement. In your case, it could be a repair and reinforcement.

The exhaust valve is the one that gets most of the attention as it can break under
race conditions.
