Roush crate engine head gasket issues?

I'm faced with a problem with the Roush engine in my Superformance GT40. Just wondering if anyone out there has had issues with head gaskets on Roush engines, or knows someone who has. Thanks.
I’ve come across a few Roush engines with some sort of issues, I believe much of it is due to poor craftsmanship during assembly, they pay someone minimum wage to put these engines together, I doubt much care is put into them
