Danny,

I bought a set of the 91112 Howard's hydraulic lifters from Competition Specialties. From the catalog.....

The Max Effort high output lifters were designed specifically for higher revving applications. Perfect for race applications which require a hydraulic lifter or high performance street applications that need an extra edge. These lifters can show a noticeable increase of power from 5,000 rpm and up. Important: pre-load must be set at .002 -.004 (warm) to achieve performance levels.

I really haven't had a good opportunity to test these claims, but Howard's has a good reputation.
