Wondering if anyone on here were using TSP's item 199-PKG1. It is the Precision Race Components 5.3L Stage 2.5 Cylinder Heads Fully CNC Ported & Assembled With Stainless Steel 2.04" Intake Valves, 1.575" Exhaust Valves, & PRC Dual Valve Spring Kit with Titanium Retainers. I am wanting to do the magic stick 4 with this combo.

Give me your opinions please!
