2003-04 Ford Mustang SVT Cobra 4V Driver LH DA 4 Thread Head, 56K Miles 221
4.6 4V Driver LH DA 4-Thread Head, 56k Miles
Came out of early 2003 SVT Cobra w/ 56,xxx Miles
This IS one of the revised heads from the Recall for the Notorious Head Tick that plagued early 2003 cars.
Revised "DA" version heads were introduced at the beginning of Dec. 2002 production via factory installation or dealership service bulletin/warranty. Revised heads often indicated by Blue Stripe along exhaust/intake ports.
If of concern, google differences between "AG", "DB", and "DC" heads
4 Thread Heads are good for stock/ported Eaton and up to a 2.2 Kenne Bell. Any bigger, would recommend going w/ 9 thread heads off 10th Anvi Cobra's or 2004 model year cars.
