There weren't extra studs in the valve chest - it's just broken across there.

Hi Charles,
May be good to try get a vintage block, I understand the material is closer to chromidium.
Would hopefully be stronger.
What are the two drill holes between 1&2 and 1&4 that's were I thought you might have put extra studs.

Tony I have seen these two drill holes in late blocks and crankcases, I always assumed they were there to increase the old mist in the valve chest.
Dave, I was suggesting using SAE Grade 8 bolts which are an much higher tensile than metric grade 8.8
