What is the truth on LS7 head re-work Bronze guides....no bronze guides....
Treat titanium intake valves....just clean them
Single BTR springs....dual springs...
CNC port....don't waste the money
Call American Heritage Performance, Advanced Induction, Katech, Texas Speed, WCCH and they ALL they'll you something different. What's one to do!

badazz81z28,
The truth is this, the powdered metal guides that come from the factory are flawed. Over time they eat the valve causing them to fail. The guide eats the valve, not the other way around. Easy misconception.
The solution is to replace BOTH the intake and exhaust guides on EVERY port (intake/exhaust). The Del-West titanium intake valve from the factory is fine, the guide is not. We re-use the intake valve in our stage 1 package and upgrade the exhaust side to a Manley valve.
If you have any other questions feel free to fire away. If you check our FaceBook page "Frankenstein Engineering Dynamics LLC", we actually went Live yesterday and talked about this EXACT issue.
