'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.

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.
