alright im trying to find these gaskets were do you get them from because like autozone and advanced have felpro

 

OEM? Have you tried from Ford?

 

Call Ford up. Make sure you use Stage 8 locking bolts too.

 

Call Ferd!

 

I installed bbk longtubes and they have the 3/8 thick flanges,and the guys at hi tech motorsports told me not to use gaskets and just use copper rtv. and its been working great for 2 years now!!!

 

I used Percy's "Dead Soft" gaskets and stage 8 locking header bolts. IMO I don't see how anything can beat that setup.

 

wow, I didn't know that OEM gaskets may be the best for headers. I hope my BBK gaskets hold up well because I don't want to feel like I wasted my money.
Can anyone tell me why OEM is better than aftermarket? I'm not sold yet...

 

I used I believe Mr Gasket Coppers may have been fel pro but Im pretty sure they are Mr. Gasket. I have had these on for 2 years now with no problems but that is also with an awesome set of stage 8 locking header bolts. The bolts were expensive but well worth it especially having BBK LT's
