If your one that can't fix a cup of coffee then I highly suggest a sticky Forum for **** parts.If you lack this kinda mechanical ability to get these headers to work Rickjames then you should really highly recommend a sticky for this.This may indeed help you alot.
This doesn't fall into a category of them being good or not.There is alot of info onthe web supporting these things are sh it as s parts and there probably a-lot of other parts out there like this.I can send you 5 links off different forums stating the same as I have listed about these headers so these are a good candidate for a garbage part sticky.
