Help with my first engine build (5.9 Magnum)

Great comment, I appreciate it! I think I did save the roller lifters, but just pulled the trigger on a new stock set of roller lifters. I thought it might be smart to replace them, rather than try to reuse the old ones with 144k miles on them... I can still cancel the order, what do you think?
My build sounds very similar to yours, hopefully I get some of the same results!

If you already ordered them I'd probably just go that route. Reusing the stock lifters just saves some money but my main point was to take advantage of the provisions in the Magnum block for roller lifters. What brand lifters did you buy?
