I can get it for 120 shiped from namura. it`s standered compression only I am thanking of insted of going to .40 go with a high compression wiseco piston standered bore. Which would be better .40 .60 bore are the high compression standered bore? I was told by wiseco that i would`nt fell much between there standered bore and there .40 maybe just alittle bit low to mid power. so this lead me to asking if i should go with standered bore high comp or a namura .40-.60 bore stand compression?
