I had some Dart 225 Pro 1 heads that I was going to use on a motor I am building. Well they sold for a good bit more than I had in them. So now I am going to need some heads. I was thinking about the L92 style heads, and would love to turbo the motor in my wife's truck later on. With 500-600whp being the highest goal would that be an issue with those heads? I have heard they seem to lift but I am unclear at what power level. I have stock LS2 flat top pistons and dished LQ4 pistons, with that power level could I run the stock pistons with good rings or should I build the motor to a 370 with forged pistons stock rods or pistons and rods? Thanks
