what do I do now

What is it about the X Heads that makes them not worth the effort? Start with a different machine shop with a different opinion. What year 360 heads?

X2 I had the same issue with 1 machine shop. He said my X heads were junk. I took them to another and he said they were fine. I been running them for 2 years now. The intake port had some bad casting in 1 runner (sand pocket). He welded and fixed it.
