I just got a set of Dynatech headers for my 1999 Sierra. I've never installed headers before and was wondering if there is anything special that needs attention when installing headers. I've heard that some headers can leak and I don't wnat to have that problem. Any help would be great. Thanks

 

Here is a little write up I did of when I installed my Dynatechs. The picture links need to be copied and pasted into a new window. I'll try to fix them tomorrow so they can just be clicked on.

They're pretty easy to get on. Probably some of the easier headers to install for someone who hasn't installed headers before.

Do a search and you'll find some good info. Headers are not a difficult install but there are always a few frustrating moments. The dynatechs have a history of fitment problems but I'm happy with mine.
