Looking for advice on using Sanderson FF4 Headers on a 5.8L /351 Engine

[KYBlueOval]

Hoping someone on the Forum has experience with Sanderson FF4 Headers. I have a  1995 5.8 L /351  EFI engine and a 4R70W transmission and Rack and Pinion Steering. Sanderson tells me they will fit just fine. I sure would like to hear from Forum members with real first hand experience using these headers on a 5.8 L / 351.
Thanks
John
