I ordered some 1" thick plexiglass, that I am going to drill for the head bolt pattern and then drill tap the center for a 14mm sparkplug hole to hook up the leakdown tester. That way I can pressure check both the block and head independently, and also see inside.
I did that exact think with plexiglass


Nice! I was just going to make a small one for one cylinder, but that's better, can pressure check the cooling too.
