High Lift Valvetrain Hardware Kit for Shredder Heads - Up to .450" Lift

This kit contains the hardware needed to assemble a Shredder head that can handle up to 0.450" lift. These are the valvetrain parts used in our RPM+ and Level II heads, so if you have a standard Level I Shredder head you can by this and convert it to an RPM+.

THIS HARDWARE KIT WILL NOT MAKE YOUR BBC LEVEL I SHREDDER INTO A BBC LEVEL II, THIS IS JUST THE HARDWARE USED ON THOSE ASSEMBLED HEADS. THERE IS A LOT MORE SPECIAL WORK THAT GOES INTO BUILDING THOSE HEADS.

Included:

1x DynoCams 36lb or Comp Cams GP960 dual spring sets (eliminates valve float at higher lifts and RPMs) 

2x Titanium retainers (lighter and stronger than aluminum with more fatigue resistance)

4x Steel medium groove keeper halves (Fits titanium retainers and adds 0.060" install height)

2x Lightweight thin lash caps (Needed due to medium groove keepers)

OPTIONAL VALVE KIT:
1x 28.5mm x 2.590" x 5.5mm Shredder stainless steel intake valve

1x 24mm x 2.570" x 5.5mm Shredder stainless steel exhaust valve (sits 0.020" deeper in our ASSEMBLED Shredder heads, you may have to machine the seats in other company's Shredder heads)

*Use for up to .450" lift on Shredder head*
*Works best with at least .400" lift at the valve to avoid spring surge*
