Hey Guys

Need some advice,i did a seach but did not come up with any useful info. I bought a set of 12.8:1 JE pistons and want to know if any prep work has to be done to them before fitting. There are a lot of sharp edges and around valve some of the metal is very thin, is there any special procedures to follow or prep work before fitting. Added pictures of the areas of concern.
