I've been getting some good response from these kits over on the FE Forum. I have about 20 of these kits out in customer cars so far. These are a great mid-level kit if you want more performance than a stock FE setup and don't want to spend $700 for an Erson kit.
These come with hardened shafts, stand studs, all billet stands (complete with end stands), and aluminum (or stainless) roller tip rocker bodies that are bushed (and grooved). They use standard cup/ball FE pushrods. This kit also comes with spacers and shims to work with any FE cylinder head, including the Edelbrock heads. A pushrod length checker is also included.
These kits run $470 (including shipping to lower 48) for the aluminum kits and $570 (including shipping) for the stainless steel rocker bodies.
I would use the aluminum kits for all flat tappet cams and hydraulic rollers. The stainless kits will handle more open pressure and would be great for solid roller camshafts.
