Default MS4 cam need flycutting?

While I'm waiting for more news on the L92 heads/L76 intake, why not start researching cams? I really like the things I've been hearing about the MS4 cams, but it seems unclear whether or not they require flycutting to the pistons. I would really like to stay away from flycutting as I've heard a few horror stories, and altho I'm sure there are plenty who have done it successfully, I would rather not take the risk and join the minority who have melted their internals. I've heard two different sides saying they do, as well as people saying that you should be fine without flycutting. Anyone know the final verdict on this?

Thanks for any answers.

theres probly atleast 30 different threads already ansewring this, but stock sized valves, with no milling of the heads requires no flycutting. change the valves or mill the head then it might not clear.

I did a search and there wasn't really a definitive answer....maybe I missed the threads that did? Anywho, anyone know if they would clear with the L92 (untouched) heads?

I know the MS4 clears with unmilled AFR 205s. It might clear the L92 heads.

because the size of the l92 intake valves theres a chance that itll be an issue. do the safe thing and check it
