I'm looking to purchase an LQ9 block that's already overbored .020. I have been searching & can't seem to find any Pistons that are 4.020. All I see out there are 4, 4.01, & 4.030 does anyone make the 4.020 Pistons?

 

Rock Auto sells DNJ hyper Pistons in .5mm (.020") for right around three bills with the factory style LS2 rings (1.2/1.5/2.5)
They have pure flat tops (no reliefs) and Teflon coated skirts
Only draw back is you'll need to deck the block .015" in order to achieve close to zero deck height

 

Thanks I appreciate it
