I think he is looking for a plate so that the cylinder head can be pressurized so as to find a leak.

Yes, that's exactly what I'm looking for. To make sure I don't have any cracks and leaks.

never even heard of this before.
why would you need these plates?
For pressurizing the cylinder head to check for cracks and leaks. Same way as you would check with any other cylinder head. I just have not found any where that sells them and/or can make them. One shop I have found had one custom made but they do not recall what shop it was since it was years ago.
