flowtech headers

:welcome okay im almost bought done with my engine swap in my 87 regal the chevy small block looks so good in there but im getting nervous about the headers. i got the flowtech headers made for g bodys from jegs i seen alot of people on the internet say bad things about them( leaking problems etc.) and heard some people say good things about them. I just want to know has anyone had experience with them cause i want to know something while it will be easy to swap the headers while everythings out the way under the hood.

Thank You

I put a set on my engine in my 4x4 2 yrs ago and haven't had any problem with them other than rusty looking. I cleaned them and painted them with ceramic header paint and it lasted about 4-6 months before the rust started but, I use the truck for off road trips and mud bog's. Used the gaskets that came with them and no leaks anywhere so far.

I have had cyclone,blackjack,hedman and hooker headers before and switched to flowtech headers a couple of years ago and so far so good. The fitman was great no clearance issues and no leaks.

I have heard only good things about flowtechs. I would suggest painting them with high temp paint before you install them because the finish that comes on them doesn't usually last too long.

Make sure you use high temp paint though. I've made that mistake before, lol.

i should of known not to pay any attention to some posts on the internet, most of the people that was bashing flowtechs were mustangs owners. Also i typed in reviews on flowmasters on google and our hearing that they are horrible they dont get any flow which i think is crazy cause i have some on my truck and love them and also plan on putting on my regal. guess everyone has a opion

I have only had them on for about 4 months, so far, so good. Im using the Victor Reintz gaskets and they work great.

The one thing I did though was to use a air cut off tool with a green scotch pad and take all of the factory paint down to bare metal. Then using the Hi-Temp engine paint I put 5 coats on and let it set for a couple days. So far, this has been the best method I have used in painting headers, paint has stayed on great.....

Bownchevell is right. I called the tech line and he suggested removing the factory black coating before painting. He said that the paint that is on there is to keep rust from forming till it get's to the customer. The proper way to keep the ceramic paint from flaking off is to literly bake them to cure the paint. It would be best to up-grade to a factory coating that they offer of go with the zinc plating.
One thing they don't tell you is heating the headers before you install them and that trying to heat them with engine heat after install would void the warranty on the ceramic coating. Read the instructions carefully if you get the factory ceramic coating.
