Default Lq4 with lq9/ls2 pistons (compression height)

So I am looking to put some stock replacement style lq9/ls2 pistons in my lq4 build to bump the compression since I will be using 823 heads and an ls3 manifold. When looking at some options it appears all the replacements have a compression height of 1.325-1.326. I am not an engine wiz but as I understand it with a stock stroke of 3.622, a stock 6.098 rod length and a deck height of 9.240 these pistons would be 0.006-7 in the hole at TDC. Am I missing something? If anyone knows of an option with a compression height that puts the piston in a better position I would welcome that information. Keep in mind though, this is a budget build and I am looking for a stockish replacement option. I have included a link for the ones I found and am considering. Thanks for any help.

Every engine and engine part is different, esp ones that are mass produced. And some of those pistons are for floating pins and some for presse so youve got to make sure the piston matches the rod also.
