BX23 head assembly marks or exact same cracks?

[tshep]

Hey - got these 3 combustion areas

They seem to be same size and exactly same place, with stake marks?
Cracks or not?

FRecommend home crack test system?

I hope I'm changing head gasket for tiniest of radiator bubbles.

Any help?

They look like registration marks,

Nope not cracks.
Someone scratched those in.

Use an OEM gasket!

I was expressing hope, that my only problem was the head gasket, to explain/fix tiny bubbles.
Based on reading, and my machinist's remarks, I may have the rare 'caught it before it cracked'!

I would replace the thermostat and the water pump, because both can cause bubbles too.
