well i have the same motor and i warped my rods, luckly i didn't throw a rod... im rebulding for performance and it's gonna run me about $700......
zc pistons = $150
oem rods = $230
complete gasket/seal set = $70
stainless +1.0mm valves int/exh = $150
topline main bearings = $40
topline rod bearings = $30
fluids = $30ish
lol thats all i can afford right now...... hopefully i'll be making a decent amount of power on a reliable motor.... but gl figuring out your problem
