Any way this isn't a crack?

Honestly I'm pretty sure your kid wants to drive the car, I would redo the head and run it find another block in the mean time to build and when the time comes at least you have a redone head to slap on your fresh block. I had a simlular scratch in the bore and just ran it that way. That crack at least didn't turn out to be a crack which is good.

Well you're not wrong, he's chompin' at the bit and I don't blame him. I am concerned we're going to throw this thing together and it could toss a rod though the side. Probably not likely with the 60 hp this thing might produce on steroids, going downhill with a 80 Mph tailwind, but still a blow.

When you say the "crack didn't turn out to be a crack", did you see this post?

That's what has my attention at the moment. The original "crack" just turned out to be a stain of some sort.

Thanks
