392, need info

[Folz]

I need to know if the engine in the pics are a improved cooling block or not.
I dont have 392 heads but I have a set of a 345 so I need to know if they will work

thanks

That is a non ic block.

As for mixing 345 heads heads to the 392, you'll need to see the cc volume and coolant passages. The 345 was planned for the smaller bore and that could be a problem. The 345 will likely have smaller valves also.
I do however suspect that the heads will function but not totally sure

do you have a set of non ic 392 head gaskets? Lay them on the 345 heads and see is everything lines up.

This is the head I was hoping to use if they check out. As you can see there are still pieces stuck to it from the failure of the 345
