MS3 vs. MS4 question i know the cams are similar aside from the large difference in lift on the MS4.
MS3 = 237/242 .603/.609 on a 112
MS4 = 239/242 .649/.609 on a 112
my question is will the duration on the MS4 have any PTV issues with stock or more specificly LS6 heads as I would plan on swapping to them.
i just want to make sure there wont be any problems

I have the MS4 with stock heads and no P2V clearance problem. As far as heads go LS6 should be fine. TSP sells a Patriot LS6 Stage 1.5 that complements well the MS4. I believe it uses the stock valve sizes to prevent P2V issues but it is ported and flow pretty well.
