While my car was at the tuner, they found my Edelbrock headers are cracked at the collector, the afr was all over the place they said. I thought I heard something when the car was running but couldn't really tell.(didn't run it a lot since it was not tuned and didn't want to damage the engine) So to get my car tuned I need to replace the headers and I was not able to find any 1 3/4 primary shorty/mid length without waiting 2-3 months. I ended up going with Hooker 2055's with the 1 5/8 primaries, knowing I'll leave power on the table, but I am in a bind. I will also have to cut the air tubes off and weld up the holes. So sad that we can't have a nice selection of headers. I will be ordering Don's headers in the future when funds recover from the tuning sessions.

 

The crack can’t be welded??

 

It is where all the primaries meet into the collector. It leaks from the center and 2 sides. I am going to try and see if a shop can repair them.
