I just finished putting my top end together and checked the squish. Im getting about .0445 on one side of my pistons and .0455 on the other side of my pistons. I have checked the squish with a piece of solder numerous times and I get around the same with each test reading a .0001 or a few difference. Bascily I'm seeing a difference of .001 on each side of my piston. I'm aware that I need to test right above the wrist pins so I have tested all 4 side a bunch of times and I'm consistantly seeing a .001 difference. I know were talking about a small amount but im not sure if I should be concerned or not. Is this just typical of a bunch of parts having a difference and some being a little worn (rod eye, wristpin)

 

On a side note I did do an original mock up with one cylinder and contacted my builder and it is in the range of what my builder wanted. Yea I could call him but figured someone would know.
