Alright so long story short i have a B20z non vtec, i broke my Timing belt and bent some valves i want to find out what all am i going to have to replace im already in the prcoess of getting a new head and getting it resurfaced because it is going to be cheaper then fixing my head and replacing how ever many valves that are bent, i have my head off already my pistons look good dont really see any damage to them i just want to know if i should replace them or not and what ever else or if all i need to replace would be my head, and i only have about 500 to spend and the head that im considering about getting is off another DA its pr4 i believe would this one be good or is there another head that would work better or give me a little better peformance i want to keep it non vtec for now. Thanks in advance for any advice i appreciate it
