I understand that they aren't the best choice but I don't have the money to re-buy pistons and I need to have this engine running by the end of next month so I'm kinda forced to use these.

To raise the compression back up, can I have the head shaved some?

on a brighter note, I got the fuel cell installed and all I have to do is run the line to the carb.
