As the title says I was wondering if it would be wise to attempt a lsvtec head swap on a motor with 130,000 miles. The motor is a B18B1 from a 98 Integra LS. Will there be major fail problems if I don't completely rework and rebuild the motor? Also, how hard is the install? I haven't ever opened up a motor or pulled one out of a car (such a noob). Thanks for the input!
