You have a very good foundation. You can easily make your money back and then some if you decide not to do anything with it. That does have potential to be wicked!
Nice. To prevent a repeat of the cam/lifter failure, I recommend the newest design lifters, pure synthetic oil changes, AND GOOD filter(I like WIX #57899) at no more than 5k miles intervals. I also recommend a pair of ss365 FilterMag oil filter magnets for the oil filter. Constant supply of good, CLEAN oil is key to longevity.
