what options are available for the LS1 for flat top pistons with a stock bore , what brands are recommended and which are to be avoided at all costs

are many out there that already have proper relief setup to cope with high lift /duration cams?

looking for 11.5 :1 comp and want to spray the **** out of it

I went with LS6 Patriot Perf heads @59cc chambers unmilled and got aprox. 11.3 : 1 with stock block.

Then what you need a piston, forged and with pressure reliefs. we just call them nitrous pistons
Like Wiseco

I hear that it is difficult to find "nitrous" pistons for stock bore

Custom Pistons aren't much more expensive than "shelf" pistons, call wiseco and place your order.
