The Texas Speed website indicates that the MS4 requires valve springs with 450-470 pounds of open spring pressure. If that is actually the case, I would not run oem rockers, nor would I run stock size hardened pushrods.

My Platinum springs are the most stock rocker friendly springs available. I also have genuine USA made Trend pushrods and the Comp trunnion kit in stock, it's all on my website.

Like was posted above, springs with 450 lbs open pressure combined with stock rockers will chew up valve tips in a year of daily driving. My Max Pressure springs are 450 lbs open but I only recommend them with roller rockers, larger than 5/16" pushrods would be needed also.
