Header Gasket Part Numbers?

[SuperSpore]

Hi, Re: 1990 350/5.7 TBI SC/SB

Looking for part numbers for OEM exhaust manifold gaskets (i fear they are discontinued)
And...
Part Numbers for Remflex & Percy's Seal 4 Good Header gaskets for same vehicle.

Anything you got is appreciated... =-)

1990 TBI engines did not hasve a gasket between the manifold and cylinder head. P/N 8889134 is the Pipe flange seal "the doughnut".
Fel pro MS9275B is the number for after market
exhaust manifold gaskets.

Or a simple google search...

Thanks, makes sense why I wasn't able to find it in gm's part list. I figured it was discontinued.
Also, thanks for the felpro info, but i'm dealing w/ JBA headers with the infamous raised flange, so I'm sticking to the reusable MLS type of gasket.
Not finding compatible PN for percy's seal 4 good, so falling back on remflex as plan c.
Anyone have anything else helpful, let me know. =-)

Use the same gaskets for your headers. Exhaust manifold gaskets work way better than any header gasket I've ever used. Put manifold gaskets on manifolds and they blow,put 'em on headers and they don't. Use blue locktite on your header bolts or drill them for tie wire.

After burning up a few gaskets, I went with studs and nuts with Mr Gasket copper gaskets on my aluminum heads with red locktiie on the studs into the heads. Ultra High temp red RTV between the gaskets and the heads. I'm thinking aluminum heads may expand and contract at different rates. No issues since.

Mr. Gasket 7153 Mr. Gasket Copper Seal Header Gaskets

Mr. Gasket CopperSEAL Header Gaskets are a high quality copper gasket that performs extremely well and are reusable. We recommend this in all racing and high performance applications. They are for stock heads unless indicated, and work well in high heat and turbocharged applications.

I use Remflex gaskets in all of my projects. No leaks ever! Also the header bolts NEVER need to be re tightened

Thanks for all the responses guys... I like the Copper Mr. Gaskets, but because Mr. Gaskets have a raised flange area, and so do JBA headers, I think I'll get a better seal with the Remflex because they're flat.
We'll find out =-)... thanks for the info.

I just want to grind it, cut it, weld it, paint it, sand blast, then put it together the first time and never have to touch it again. I think it's possible.

Perhaps a moderator will move this thread to the Exhaust sub-forum.
