At least get new rings. Although I got 4k miles/2 seasons on my F7 engine since I put in a whole new topend. I don't plan on getting new pistons OR new rings anytime soon. Hopefully Cat will come out with something worth buying in 2012 and i'll sell the Firecat.800DOO said:I see what your sayin, its gonna need pistons sooner than later so might as well do it while its tore apart. Alrighty modman thanks for the advice!
