1969 Dart Street/Strip (Re)Build

I would think they will have you send them back. They might just cut that .018 off the top. I doubt it would hurt the piston at all.

They are already making a whole new set. I just don't know if they want the old ones back yet or not. If they cut the top down, we'll lose dish which will change the CR. We thought about that option but decided against it. If the block wasn't o-ringed, we could have just ordered a custom head gasket to make it work. But I'd rather they just make the piston the way it's supposed to be.
