Honda 450 head, cracked?

[K85 Octane]

Sup ya’ll

I have a nice, bench flow ported head on top of my TRX450R engine. Been with me a looooong time. Cylinder is good, but I haven’t touched the head in 250+ hours. (Good lord it could be so much more than that, I don’t know) So, while getting intimate with it today I noticed this crack. Does this look serious? No fluid transferring going on and I don’t see any external issues. Am I in for a new head and all the subsequent port work that follows? At first glance it looks like just the nose has it but it carries down about an inch into the runner.

Stops just short

Clean it, weld and smooth.

Unless a new head is cheaper.

New bare head is ~$300. Not interested in a used 04/05 one at this point. Just Valve job/porting after. Anyone know a place I can mail this to? The shop that did mine, dude retired few years after.

Even if I keep this head, it will need some freshening up. Dunno what’s cheaper.

OH!! Thank you
I didn't see they were "local". Might have to give them a call today

Wait a second. It's CA but not that local. Still 2.5 hours. I would say "hell yeah" and visit SD while I'm there but there's not much open right now lol

Only 113 miles each way. you could wave at a lot of CHP officers.
