Default LT4 cracked head

So I had to buy a new set of heads for my Z. Took a little troubleshooting for my guy to figure out coolant was coming out of one of the exhaust ports. Cracked head. They were CNC ported. Is there any value to these or are they boat anchors?

You would have to have the cracked head welded and then machined.

I don't trust ported heads, too many 'professionals' will remove too much metal leaving that area weak thus prone to cracking.

Usually cracked heads just become a heavy paper weight due to cost of repair and uncertain reliability.
