You could not pay me to put l5p heads on anything other then a l5p setup they are extremely necked down in the port area. they say it's for torque reasons down low on rpm but what happens when you try to force 12ft of air through a 6in hole at wot doesnt work for me jmho:thumb:

Their torque numbers and the fact they spool large singles faster than the 01-16 trucks kinda says otherwise. Until cfm data is released, it’s all speculation

Have you seen the l5p cut a ways James they are ridiculously small on the channel side and port side until numbers are released its a guess but from the looks of it they want flow much in stock form

That cut away is miss leading. Look at where the guide is from one to the other. It’s not cutting straight dead center through the l5p valve where the lml one damn near is.
