I am in the process of disassembling my heads to clean, do a mild hand P&P, and install new parts with my XP cam. There was nothing wrong with them before, the motor has 30k original miles on it, and had excellent compression before disassemble. I have an XP cam, with #105 springs, titanium retainers, comp cams valve locks, valve stem seals, also a new OEM timing chain and dampener on the way. I planned on reusing the stock rockers, valves, pushrods, and lifters. Is there anything I am forgetting? Also is re using the parts I mentioned advisable when going with this setup? Thanks for any advise or input!
All the exhaust valves appear to be in the same condition, the first two pictures have been cleaned. The third shows the uncleaned valves, so should they be replaced? also any explanation as to why two of them are a completely different color compared to all the rest that are covered in carbon buildup? Could it be because maybe they were from the cylinders furthest from the EGR?
