I also had a question for when I install the pistons. Which way does the piston go? These pistons are flat top and don't have an indicating mark on the piston for which sides goes to the front.

They were all numbered and this was my best guess for their orientation

This is in the same orientation, and here's the tab on the rod cap.


The only markings on the piston are on the bottom and it's just a number etching


Nothing identifying on the face of the piston
