I searched and read here...any further testing? Looks like a proper cam profile can smooth the lack of low end due to big intake runner volume. The comment that they come on like a lightswitch at 4500 was made. I just think it may be a 'win' with these if I debate on doing a 2.3 tvs blower on down the road. Even if I don't, they still make HP! My alternative purchase would be the TFS or Livernois St3.

I don't think you can go wrong with a custom cam spec'd for the MAST heads. Properly setup, they will make some steam.

Think it's too much intake runner cc for stock cube 346?

They were made for the 346, so no, I don't think they are too big. Cam valve events can help the low end if you are worried about power under 4500 rpm's.

That's what I was thinking I just wanted to make sure I am understanding right. Shifting the power band like that with the cam to compensate for 3-4k shouldn't pull too much away from the top end I wouldn't think.

Just do yourself a favor and have someone set you up with a custom cam to optimize the heads and overall setup.

Ed Curtis has done several cams for the small bore LS3's and I've not heard a single complaint. Then again you never do with Ed.
