Guys we're proud to announce after months of development & testing that the all new PRC LS7 cnc cylinder head is complete! The PRC LS7 cylinder head was built for big cube ls engines wanting the maximum possible cylinder head flow for the dollar! With 390+cfm air flow capability this all new cylinder head is set to be the leading head choice for these new big cube LSx & LS7 based engines.

Extensive valve testing has resulted in an all new hollow stem valve option to help keep both price & valve weight down! No longer will it take $3000 to build a LS7 based cylinder head for your big cube project!

Current price on the base PRC LS-7 Cylinder Head is $1699.99 with standard stainless REV valves & stock LS1 springs. Upgrade to the all new PRC hollow stem valves & PRC double spring kit & the complete cylinder head kit is only $2199.99!

Here's the options available with these cylinder heads:

Stainless Valves / Titanium Valves / Hollow Stem Valves
Standard Spring / 928 Comp Springs / PRC Dual Spring Kit

Here's Flow data for you guys!
