From most posts I have read they say it fits with stock heads. Just have to upgrade to some good springs to support the lift on that big a$$ cam.

Fits without a problem. You'll love how it feels. Just make sure everything goes back together right. However, I also wouldn't recommend doing it on a 150K+ mile motor.

I'm about to put it in my ls2. I'm using double spring valve springs, doulbe roller chain and ported oil pump for added security. I've read you can go with stage I heads but stage II heads wont work w/o flycutting. Not sure the difference between stages and if stages are the same between all companies.

I cant wait to get this though. Adding an UD pulley and porting the intake and tb also.

Just get the entire cam kit from TSP. Doesn't get any easier than that.

It will fit stock cubes and Jason from TSP says will not have fitment issues. You will need PRC double spring or any others rated at .650 lift or greater, Chromoly pushrods, and a new timing chain set. I suggest an LS2 kit if you want i have a MS4 in GREAT shape for sale. Has 3500 miles on it but you can see in the pics it's almost perfect. Asking 275 shipped for it. Thats $115 less then new BEFORE shipping I bought it off another member here and then decided it was too much cam for my needs so before i even got to install it i decided to resell and go with a smaller cam. Shoot me a PM~Cole~

Get atleast 4.10s cuz i see ur m6 and I might add one more thing in the upgrade is get some ls7 lifters. The cam will fit stock heads with no problem or flycutting and you will need prc dual spring kit comes with titanium retainers. Give texas speed a call they will hook u up with everything you need.
