You will certainly need new valve springs at least to handle the lift and rpm. (mentioned by TSP) I would do the Trunion change while in there. DON'T mill the heads or get a thinner head gasket, or you will have to get fly cut pistons at that point.
You will have to get a full tune and raise the RPM limit to take advantage of the extra power that is past your stock RPM.. otherwise, there's no point to using the cam.
Then, with the higher rev limit, you will need to look into rod bolts. Not an absolute, depending on the year of your motor, and trust in the newer stock rod bolts. Higher stall if it's an auto or bog everywhere you go.
Then... tell us what you think.

If you drag, it's a great cam.
But then you'd need 1-7/8" headers, true duals, FAST 102, Yank PT4400 + 4.10s, lightweight valvetrain + high pressure dual springs... yeah, it would scream, but it'd be a bitch to drive around.
Also, LSK lobes are a bit much on the LS1. The LSL, LXL, and others recently released by Comp are designed for the 55mm LS1 cam journal with lots of spintron R&D on valvetrain harmonics. They have similar ramp to the XE-R and LSK but are much less prone to bouncing off the seat or closing harshly... all creating better control for a hydraulic application.

My 224r has beat more MS4 cars than I can count. All the guys love to brag about their MS4 because bigger is better right. Then they race me and tell me I'm lying and running something bigger than a 224r, or I have a cheater nitrous system hidden somewhere.

Ok I am going to throw this out there YES bigger isn't always better YES yhe ms4 is a max effort cam and you need all the supporting mods for it or it will be a dog. NOW just like every other cam out there you need a tune true it is hard to tune a ms4 cam but it CAN be done but it is not only the tune and cam that make your car go fast its all the other parts of the puzzle. You need and intake heads and exhaust that flows like hell. A stall to get you to the power band and gears. You will have to keep track of you valve springs I have been thinking bout the ms4 very hard also but i know once again you need all the peices of the puzzle like for me that will be prc 227 heads, .675 springs, hardened puchrods, fast 102/102, yank 4000, 9in 373 or 410 (still have to check in to that), trunnion rocker upgrade, double roller timing chain, ls6 ported oil pump, trans cooler, and a new block articles and bored to 383 or 408 (have to resleeve for 408), fast toys 104mm lid, this will be my set up NOT CHEAP TO HAVE A BIG CAM BUT IF YOU FOEVEYTHING RIGHT AND NOT HALF *** IT WILL PAY OFF FOR YOU

I have the ms4 cam.
Do i recommend it? no,
nice sounds but the power band is way to high for my taste.
you cant just "jump on it" and get going it takes a bit to "power" up
my set up is on my sig if you got any more questions.

The OP is not the only person running the MS4. It is a great cam that puts put great power, that was the positive argument for the OP. the neg is he needs some supporting mods (heads, intake, lid, maf, TB, stall, gears) and using the right ones this car will scream! And a large cam can be a PITA to drive around on the street, especially in an auto. In an M6 it's manageable

People are just telling you THAT CAM SUCKS FOR YOUR SETUP its true. It will sound good and thats it. u're going to get u're *** kicked in that weekend worrier. I'm not trying to be mean just listen to people we've been there already or know someone that has just trying to help

I wouldn't recommend a MS4 for a stock high mile motor thats mainly street driven. Unless you have the supporting mods and were talking everything then get you something like the El Toro or a 228 TSP grind. I love mine but it loves high compression, 4000+ stalls and high gears. It won't wake up until you get a good set of heads and a bigger intake. Mine picked up 27rwhp just going from a LS6 intake to a FAST 90/90.

Guys, it has always been, and will always be about the entire combo! There will always be 224º duration cam guys bragging about walking on MS4 cammed cars because they didn't get the supporting mods. Look at our racecar, stock bottom-end LS1 with just heads/cam and it'll walk on 95%+ of the stroker and power adder cars on this forum because we have the entire vehicle setup to race and the combo works. That doesn't make stroker engines or power-adders less legitimate though!

Well comparing a gutted race car vs. 95% of the cars here that are mainly driven on the street isn't fair either. Of course it's about the entire combo but for the OP right now, it sounds like the MS4 is a bad choice.
