i need help with bbc headers gaskets ????

so i put the bbc in the 56 bel air ..after running it for a little bit i realized there is a header leak ..i used the blue high performance fel pro gaskets and am trying to find the thicker aluminum type that will cruch and seal so this leak will go away its ruining the finish on my white headers with the black carbon....any links or pics will help

yes i used the good header bolts and yes they are super tight ..if i tighten them anymore i may snap a bolt in the head ..they are square port heads

 

I use to have a motor home with a 454 in it. It would push out the header gaskets one after another. I found a guy that sold graphite header gaskets and they lasted for ever, I was even able to take then headers off once and they were in perfect condition. Do a search for graphite gaskets, maybe you will find them. JC

 

ive been searching all day for these gaskets cant find anything

Mr Gasket makes a steel reinforced gasket that work great. Using them for years with excellent results.
Part # 5910 - Mr Gasket Ultra-Seal Exhaust Gaskets

 

the felpro gaskets im using look like the percys ..and they leak the ones i need are like 3 or 4 layers thick ive used them on turbo manifolds but cant find them for bbc headers

 

I have a set of Multi-Layer-Stainless Steel Fel-Pro brand header gaskets on my TT BBC. They stay sealed real well. Unfortunately I can't find a listing anymore.

Cometic makes them too: http://www.summitracing.com/parts/CGT-EX157SPB030S/

 

How thick are the flanges on your headers ?

 

actually sealing surface is a good point.

My headers are 1/2 steel and dead flat on the mating surface. I had a problem with burning out the Ultra-seal material and the bolts would loosen up. Since the MLS gaskets, everything stays tight.

I have fixed a few sets of headers that have the tube protrude through the back and end in a "metal O-ring" as some of the header manufacturers like to call it. But the sealing surface is thin in spots, if it seals at all!

Might be a good idea to check that stuff out as well as looking for warpage of the flanges.

 

I've run the Fel-pro blue gaskets with my BBC and long headers for over 56,000 mi with no trouble whatsoever. As said check for warpage and also sealing at the header tubes

 

my headers on my 427 had 3/8 flange never really had a problem with gaskets

 

i couldnt tell ya how thick they are they are square port heads though. also my problem is that the tops of the headers even when tightend down to the fullest torque dont fully connect to the heads matte surface thats why i need a thicker gasket its not much of a space but its enough to leak ....someone said double gaskets but i doubt that will work and i cant find the gasket im looking for ...wtf

 

im sure the headers are warped

 

X2...These are very good gaskets and available most everywhere including O' Rielly's

 

AH!

Yeah, your headers are FUBAR from over-torque-ing and need to be straightened out. No amount of gasket is going to fix this situation.

 

i dont think their fubar ..i can stick a penny in the space thats not that bad ...lol

 

Uhm, no, that is bad.

I get you are kidding, but in all seriousness there can't be any gap. When there is a gap there is no surface compression and all gaskets need that pressure to stay sealed.

 

A new set of gaskets and 8 cents and you'll be good to go.

 

LOL, reminds me of an engineer joke. " We built this thing to tolerances a thin as a dime. When we ran out of dimes we used two nickles. "

 

lmao.....thats what im saying ,,,,but i cant find the damn things i need ....

nah i here you elpalcko...but i cant afford new ones

 

lol

 

you don't need to buy anything, fix yours.

All you need is a hammer, straight edge and some patience to get them back in line.

 

wich i have non of ...patience im out of ran out back in may.....i still need thicker gaskets though

 

if you can take your headers off put a staight edge from one end to the other on the flange that will show you what your working with

 

im beeing lazy and done want to pull them back off to much trouble was just trying to loosen them up and slide a new gasket in their

 

Give up and use Red RTV silicone then. Put on a thick bead around each port and let it set up overnight before you torque them down.

You just are not going to find a thicker gasket than what you have already.

 

will that even work never tried that usually i always do things to my perfection but im burnt out on this car and before i lose interest in it i want to drive it ..maybe to gaskets and the rtv sealint you are talking about?

 

Done it in a pinch, it does work.
