LQ4 question Morning!
I am building a LQ4 and plan on installing a turbo down the road but for now I'm keeping it N/A.
I am going to be buying forged pistons soon and wanted some help on selection. The only reason I'm asking is because i have 243 heads. Should i buy a dished piston and run the 243 heads when i turbo or should i run the 243 heads for now(N/A) and switch back to the 6.0 heads when i turbo?
I am asking this for compression sake.
Thanks!

If you have the engine N/A I recommend using a stock cast piston engine. No reason to wear out forged slugs on a motor that doesn't require them. Build the forged engine on the side and keep it for when you actually need it. the cost of a spare engine block to build is negligible compared to the cost of parts/assembly, and wear/tear.

Heads will depend on what pistons you go with. If you get flat tops, 243s and a turbo won't mix well unless you stay on low boost.
If you're doing pistons, you might as well do rods. They're cheaper than pistons are more often the weak point.

I am not saying put stock pistons in the engine you are building,
I am saying put a stock engine in the vehicle until you have everything you need to take advantage of the built engine with forged pistons you are building.
The cost of the build is $8k+
The cost of a stock engine is $500~ insignificant compared to the cost of the build
Sort the car out with the OEM engine then swap in the big one when ready to pay for FI
