Super tech titanium retainers part number K20A2/T2 were used for the maximum strength with wear and chaffing resistance while retaining lightweight to reduce the chances of valve float.
Even though they are little parts, the valve keepers are one of the most critical parts of the valvetrain. If they fail a valve will drop and destroy the engine. Supertech keepers part number KPR-5.5/7A-ST are not stamped like cheap OEM parts, but machined out of chrome-moly and heat-treated afterward.
Supertech valve spring seats part number H1020DS keep the inner valve spring perfectly centered.
Supertech valve seals part number VS-H5.5E and VS-H5.5I are low friction, heat resistant and still seal well for low oil consumption. The intake seals have more tension to keep oil out of the intake ports while the exhaust seals can tolerate higher temperatures.
For cams, we used Drag Cartel Stage IV parts. The part number is DC-OG-004. These cams are ground on 8620 steel billets. They are CNC ground with small diameter finishing wheels to give the proper inverted flank ramps needed to work well with roller followers.
The Drag Cartel Stage IV cams have a whooping 275 degrees duration at 0.050″ lift and 14.5mm lift on the intake side and 275 degrees duration @ 0.050″ and 13.2mm lift on the exhaust side on the high RPM lobes. It’s a good thing these cams have i-VTEC to help out on the bottom end! The Stage IV cams are stable at high rpm and are suitable for road racing and long-duration events.
