I talked to TSP today about this. Aparently I was right... The MS3 will work with 5.3 Stg2.5s with out a valve cut deeper. And no Fly cutting is involved. However, like in this situation, when you order the Torquer V2 with the PRCs, they did not cut the Head to the valve clearance they see fit. TSP DOES NOT RECOMMEND you run the MS3 with the PRC stg 2.5 5.3 heads UNLESS you have the "Valve Job". But they will still clear.
Did you talk to Trevor @TSP today? What he say?

When you ordered your 5.3 heads did you specify you were going to be running the MS3??
I didnt talk to Trevor today. I talked to John who said Trevor was at a meeting and would have him call me back, but he didnt call back.
Yeah, normally, you want to get your head assembled to the specs of your cam...
They say it will clear, but not by very much,and TSP doesn't recommend you try it, you will have to send them back, and have them cut the valves a bit deeper...

Yeah but I dont want to take my heads off again. I did them myself and I promised myself after I put them on that Id never do heads on an LS1 again, so theres no damn way they are coming off.

Overlap is 5 degrees. Intake closnig point is like 49 degrees. I need something with higher overlap and an earlier intake closing point and a later exhaust closing point to build compression quicker to fully take advantage of the heads.
Joey like I told ya im willing to bet after all this you pick up a max of 10hp. Like jwall and I told you get your **** tuned for the nitrous first and see how it does. If you put the MS3 in without doing the head work, and miss a gear you pistons are gonna kiss those valves then your really gonna be in trouble

^ ahh, I'm not sure about that, My prc heads and MS3 cam put down 462RWHP SAE.... I have a all the same **** he has and my motor had 104,000 miles on it... So, what did he dyno again???? hmmmmm
Another guy with same setup put down 471rwhp on the same Dyno..
PS, I dynoed 458 on a Mustang dyno with the same setup, so I ask again, what did he put down with the current setup and tune...
Maybe TSP can cut you a Half off on shipping, they do that kinda **** all the time...

I bought a set of PRC 5.3 stage 2.5's wanting to run a MS3 cam and now realize I can't. So the ONLY option is sending the heads back or getting a different cam. What is a good cam recommendation, I was set on the MS3.
I might just sell the heads and buy the package deal this time.

You have to specify if you are running the MS3 with the 2.5 heads...If not, there will not be tollerable clearances...Will it work yes, but for how long is the question...
As for the MS4, it will not work with the 5.3 heads, or the LS6 stage 2.5's, due to the bigger valves, however they will clear with the LS6 stage one heads...
I think it would be wise to either pull the head and get the valve job done, or go with a different cam that wil fit...
TSP has some very promising packages that perform...I wonder what package I am going to go with
