To minimize issues with quality of castings, we will source all cores used in the CNC Program.
This is for a pair of CNC ported heads, with castings included, complete with reconditioned OE valves and PSI or PAC Valve Springs and Retainers (OE, or Ti when available). We use an aggressive valve job for maximum valve clearance and extra shimming on PSI or PAC springs for max effort setups. We have seen 130+ whp over stock with heads/cam/Hi-Ram and supporting modifications on a stock piston N/A 6.4.
6.4 heads flow ~400 cfm @.650 lift (intake).

Paid consultation is a great way to filter out tire kickers, I support this 100%
Everything come packaged well and was all there. Still working on the install. Can't wait to see the gains!
Ryan got me squared away with a list of everything I need to reach my goals for my car and also informed me of modifications that are unnecessary for my project.
