This seal came from a new set, it seamed like a decent seal, this set even had a copper head gasket. felpro was the brand. I would agree that all 235's leak to some extent. My 216 in my 37 truck leaks less than this one. It just is a little bothersome that you put all that time in cleaning/painting the 50 years of road grime and dirt. Then it leaks on the first 20 minutes of running. I will run it for awhile and see if it seals up. I did remember that I rolled the seal into the grooves with a socket, then cut the seal slightly above the deck and cap.

We will see what happens.
