Lady's and gentlemen,

Been looking on the interwebz at various pistons available for na 4age. I've come across a fair amount of dished turbo/blower pistons but not a lot in the way of decent high crown na ones.
One result that I've come across are wiesco ones but honestly I've never used then before. Thoughts? As long as there a 20mm pin and maybe .5 - 1mm oversize.
Was hoping for more of a off the shelf but may be a custom job.

Thoughts?
