Cylinder Head Crack Still Usable??

Thanks al!! We'll tear down and rebuild is occurring and I noticed one more thing. As I lapped the new valves I noticed the intake seat on that head also has a nick on it. SMH

It does look like someone did a bowl blend or an attempt at it. It looks like they nicked the seat with the porting bit.

Can this be ran as is or is it a problem? You can see where the valve lap didn't really cover it.

Unless you just need to throw those heads on an old stock engine to keep it going I'd take them to a machine shop and get a valve job done. Lapping makes the valve job worse anyway, I'm still learning about cylinder head machining but those seats look wide as hell, and only 1 angle on the INTAKE? You'll make more torque and power with a decent fresh 3-angle valve job for sure, compared to what you have now.

Looks like they succeeded at smoothing over the chamber edges at least, that's a good thing.
