Hello all, looking for some advice on issue on my lil brothers Ram. its a 2009 1500 SLT, 4WD, I believe it has the MDS thing, its his daily driver and he is 21 and in a rough spot with this issue. For clarity purposes I am a Mustang guy, and my knowledge of Hemis is somewhat limited. (please don't forsake me 
) Bro called me up and said he had misfire on 1 and 4 cyl. Truck ran like **** and doesn't know what it is. I went through things I thought would be most likely, spark plugs, coils, etc... I live in Cleveland, OH and he is down 2hrs in Columbus. He has little to no mechanical ability and so talking him through things was tough. Ultimately a family friend who is more mechanically inclined came to replace plugs test everything etc... they replaced plugs, swapped a few coils around and got #4 to stop throwing code. After all said and done still sounded and ran like ****. everything electronically is sound per testing according to the mechanic family friend. Him and I were in agreement that the lifter failure problem with these engines is probably to blame. I believe one or more lifters seized and scalloped off the cam lobe. so those two cylinders are not operating as they should hence the misfire. So I had Bro tow the truck up to my house in Cleveland where it sits now. I intend to remove heads and replace lifters/cam. Its cold a balls outside and not getting warmer. So I want to make this repair as fast as possible to get him back on the road and me get back in the house. My question to your forum community is tips/trick to making this easier? also intend on putting in stock replacement parts, but I have been reading you can put a beefier cam in and get a significant performance gain in these engines. I am curious if their is a no tune required option for that, or if you are stuck getting a SCT or similar to tune the new cam if you go aftermarket? trying to get best bang for buck "while your in there" repair if its not too much more cost.
Thank you for your time,
