We are now offering a free upgrade special on our PRC stage 1 LS6 heads, for a limited time when you buy a set of stage 1 LS6 heads you can upgrade to a stage 1.5 (larger stainless intake valve) for FREE!! From now until the end of the month we will be offering the PRC Stage 1.5 LS6 heads at the cost of our stage 1 heads, that is a free upgrade in intake valve size (your choice of 2.02" or 2.04"). The heads are $999 with the competition valve job, assembled with LS6 springs or $1250 assembled with the PRC dual spring kit (PRC dual springs good to .660" lift, Titanium Retainers, Hardened seats and new Valve seals).
