which gasket for headers?

i just got hedman headers in the mail

it came with 1 paper gasket

i also bought a felpro gasket kit that has 2
1 for intake 1 for exhaust manifold?

is that right? do i need to use both?
and in which order?

should i double-up hedman&felpro w/copperRTV
for a better seal?

starting the job today

thanks for your input.

Re: which gasket for headers?

I'm no expert but I have never had any luck with the top gasket (metal one) sealing the exhaust. The bottom 2 look better to me. Some rtv on the intake gasket couldn't hurt.
The only exhaust gasket that lasted for me on an AMC v8 is the solid copper ones.

Re: which gasket for headers?

I hope I'm not too late. Learn from my mistake. I bought the Felpro kit thinking they had to better than the paper. LOL exaust leaks. Replaced with the Headman gasket and things are nice and quiet. It's a better gasket than it looks like at first. Just a side note. I had to do some minor grinding down of the ears of my intake to match exactly the thickness of the flange of the headers. This helped tons with getting them to torque down right and stay that way. [img]images/graemlins/grin.gif[/img]

Re: which gasket for headers?

thanks for the help!
I'm going with the paper gasket from hedman for the hedders
and felpro for the intake. problem is...

I'm in the middle of the install, I just went to put
the intake manifold back on, having aligned the gaskets & hedder pipes and it doesn't fit!

the flange on teh bottom of the intake hits pipes 3&4

so... i need that grinder, back to the store.

Thanks again

Re: which gasket for headers?

I used only the Hedman gasket. As I said I had to grind some of the ears of the intake so they were flush with the header flange. Using double gaskets on the intake may make this problem even worse... but it sounds like you've got other issues too. Good Luck [img]images/graemlins/grin.gif[/img]
