Looking for the best performing LS2 cylinder head/manifold and camshaft package on
the market today at a fraction of the cost, look no further! Through extensive dyno testing
and flow bench research, this package builds on GM's new technology, designed specifically for
use with stock bottom end LS2 engines, SLP's L92 cylinder heads are surfaced milled and
come with a CNC'd finished chamber. The combustion chambers are set at 64cc's (stock 70.2cc)
and come with SLP Valve Springs (SLP# 53003) which are set to the proper
install height and titanium retainers (SLP# 53104). Also, included are eight L92 offset 1.7 intake
rocker arms and two L92 rocker arm pedestals. This camshaft alone over a stock camshaft with
L92 heads makes an additional 26 HP at its peak and it's largest gain and has 25 ft-lbs of
torque at 3700 RPM and 5970 RPM with 14 ft-lb of peak torque. With the proper tuning, this
camshaft will idle down to 750 RPM while providing unbeatable mid and upper range power.
