Is there an off the shelf piston (it's a 347) that will get the compression in the 9-9.5 range using a 58cc head? I already have ETP heads on my motor that are milled down and i'm kinda getting bored with nitrous...

I'm sure there is. Use this calculator to figure it out.

Example for specs of my engine: Head gaskets set to .050, deck height on my engine is .015 in the hole. Stock LS1/2 stroke is 3.622. Just fill out the rest for your combo.

Do you know what the spec is for how your pistons sit in each cylinder? My builder put mine at .015 down in the hole. It makes a big difference on compression what that spec is.
