'Restricted oil flow' pushrods were developed especially for the hydraulic roller market. Our engines begin to experience varying degrees of valve float at 6,000 or fewer RPM'* due to the inertia mass of the roller lifters. INTENSE™ Oil-restricted Pushrods are constructed of 4130 seamless chrome moly, feature a .080" wall thickness and weigh 595 grams per set of twelve (approximately equal to the factory rods). The rocker arm ends are 210 degree radiused and there is a specially metered oil hole. This oil metering works to keep the lifter 'pumped up', and allows the engine to operate at higher speeds with less chance of a failure. These are the best choice for customers with any sort of power adder and/or full roller rocker arms.

And raised shift points via PCM.
My new pushrods are restricted, but not to the extent of INTENSE'* S2 rods. Mine were made custom for me by the same company that makes theirs.

Talk to INTENSE about Lifters and Valve Springs when you do the rockers and pushrods. You'll probably want OE-R series lifters and stronger springs. It'* really a whole package.

I've heard that the OE-R lifters tend to tick and new stockers were going to be my choice. What type of lifters are you going to be using Will?

CompCams OE non-R lifters. But my pushrods are slightly oil restricted. OE are supposed to be a performance upgrade to OEM lifters, more durable, more consistent with raised shift points.

FWIW, I have stock lifters and pushrods on my GT with 90lb. valvesprings and I have spun it to 6800rpm on numerous occasions without any problems at all, doesn't seem to have any valve float, and makes very good power at those rpms as well.
