Crack in 1938 Head

[slamiste]

Hello,
Attached are a couple pictures of a crack I discovered while bead blasting the heads for my 1938 EL. The crack starts at the exhaust port and continues to about 2 to 2.5" from the valve guide hole. My questions are:
Is this common?
Should, can, this crack be "repaired"? If so hows the best method?

I've been working on this project on and off, mostly off, for about 5 years now. The heads are my biggest reason for not making any recent progress.

Thanks for any help !

My 47 Knuckle had the same problem on the front head. Extended almost to the valve seat. Also had a crack between the two valve seats on the rear head and a broken lug on one for the rocker box. mount hole . I found on the internet Midwest Cylilnder and Head in Nevada, Iowa. They have a website but at the time they also had a facebook page that showed a knuckle head as it was repaired. Sent both of my heads for repair including new valve seats. Seems like it took 4-6 weeks. There work was remarkable and I feel very confident. Expensive but I was told to buy replacement heads and am glad I didn't.
