U will need new hardened push rods and roller lifters for sure and headers and a ls6 in take for sure to help cam breath custom tune as well air fuel ratio if possible

I would send your 243's off to AI to be ported, have a valve job and milled alittle. You will need hardened pushrods, also if your car has higher mileage i would get some Ls7 lifters to be safe. I would get some injectors and a racetronix 255lph fuel pump while your at it.
