Reply to "How sketchy are the stock valves?"

I bought at Realstreet Performance:

- Intake: 8 Manley 11872 at $139.20

- Exhaust: 8 Ferrea 6000 F6124 at $153.92 instead of $238 for the Manley 11805 which weighs the same weight (108 gr).

The Ferrea 6000 for intake are more expensive (155/139.2 $) and heavier (145/129gr) than the Manley.
