Have not ran it yet, but first look at it shows a few issue.
The head that comes with it is not oring'd like most h20 kits, instead it comes with a head gasket. The head is also much to small for the cylinder and needed to be cut to match. Gasket was super crooked and need to be fixed as well if you wanted to run it. I think I will be cutting oring grove into the head instead though.
If you want plug and play, buy something else. If you just wanna save a few bucks and are able to fix this thing up, then get on for sure! I will update when I run it, definitely looks promising.
