Hey, new here, im building a LQ4. 2007 block, L92 heads yadda yadda. Anyhow, i CNCed the Block yesterday and went .020 over without looking at the fact that i cant find a .020 over piston! Does anyone make a decent 4.020 piston or should i put it back on and just go .030? Using stock crank, yet to order rods probably going Callies

Wiseco has a few 4.020" pistons listed here.
