I have a set of 10.5:1 pistons for sale, they arent forged. I do believe stock pistons are forged so no reason to replace them. Valvetrain I dont know about. Ive seen some nismo valvetrain stuff on a site before but I dont have the link handy.

Stock pistons are cast, not forged.

But they hold up well under boost, so most N/A apps will not *require* new pistons other than for a compression change.

And Bussman - You can use the SOHC pistons to get a static compression ratio of 11.1:1...off the shelf, OEM parts.

we use Arias pistons and rods in every motor we build.They hold up the best under extreme boost applications.

This is the all motor section, I doubt he is trying to get his engine to hold boost.

boost, nitrous, high compression... Any situation that could result in detonation weather premature or as a result.
