Ok, finally going to get my cam swap started and need to know what parts to order. Truck is a 2012 with a 5.7 and 182,000 miles. It still runs good but it has developed the chirping noise. I'm going with a 6.4 cam and lifters, timing chain and oil pump. Thinking valve springs and push rods too. Will the 6.4 springs and push rods fit? Besides new head bolts are there any other bolts that should be replaced? Anything that I'm forgetting? Gaskets, are Mopar parts better than over the counter? Thanks for any help.
