We order our heads bare, port them to your application's needs, do a multi-angle valve job on a Serdi valve machine, then fit them with Ferrea valves, Comp Cams spring locators, Viton valve seals, Comp Cams beehive or dual valve springs, Comp Cams steel 10° retainers, and Comp Cams steel 10° locks.  Each cylinder head pair is set up specifically for your camshaft's spring pressure requirements and bore size.  You can buy our heads by themselves, or buy them with a port matched Performer RPM, Dove Tunnel Wedge, or Victor FE intake manifold.  When comparing prices, be sure to compare the brands of the parts that are used in the cylinder heads. 

Our Stage 1 heads use 3/8" Ferrea valves and are ported to flow approximately 305 cfm on the intake side.  Stage 2 heads have 11/32" guides and Ferrea valves installed and flow 320 cfm @ .650".
