Trust me, mine aren't perfect, you need to look closer! Ha ha, thanks for the kind works though. I can't see the imperfections in the roof pic? They can't be that bad?
Some 5k's came factory with flat top pistons and chambered heads, not too sure if you can buy them (pistons) new, only other option would be to get a 5k head to up the compression back to where it suppose to be.
cheers!
