    I also put on a pulsar lt, so far so good, gas mileage went up from 16 mpg to 21 mpg. If you have the extra coin I highly recommend it. Hopefully my valve springs are good. Thanks to all the guys that have posted

    I have a little over 5000 miles on my 6.2 On 6.2L engines (RPOs L87, LT1, LT4 and LT2) built from June 1, 2020 to October 7, 2020 does anyone with that build date have a lot of miles and no problem yet?
