9 thread heads

[Dib14gt]

I have a 03 10th anniversary coupe. Reading that some of those had the 9 thread heads because they were a later build. Does anyone know the build date those heads started? Yes I know pull a plug and count the threads, but it’s cold as shit here in pa..... thanx

That link above is to my site - there are pictures that show you where the casting numbers are. You don't need to pull a head, just get a retractable mirror in there to see the number on the head (or you should be able to see them from below if that works).

As for the dates, the Anniversary cars were built in June and July of '03, so it's a toss-up whether you'd have the DB threads. I've never been able to find out, probably because the info doesn't exist, but it's safe to say that the later builds in that period are more likely to have the newer heads. Really though, you just have to look for the casting number to tell.

It is easier to pull the driver plug cover and remove a plug. Literally takes 1 minute.

Lift up the car check the casting numbers. Easiest way to go.

I used a mirror and flashlight to see the casting numbers. seemed way easier than jacking the car up.
