My 97 LT1 has worn Street and Performance header gaskets and Patriot Headers ever since it started running. Neither the stock nor BBK headers will fit the tight confines of the car. It's not a race car. And I had a time of it making the headers fit the idler arm area as well as the pitman arm area. Anyway . . .
S&P is gone and I need new gaskets, but they must have been Specialty Gaskets and seem unavailable OTC. They are oval port gaskets that measure 1.62" x 1.35".

Would anyone know where all the S&P stock went of where/who makes a gasket like these?
Thanks.

Not sure what to say about your not being able to get stock or BBK (I'm assuming for a f-body) headers in the engine bay. I don't remember what's all entailed, but I think you have to go throught the bottom the passenger side. Y-pipe (if stock) has to come off for clearance. May be able to get the drivers side through the top. All kinds of writeups if you do a search.
If the heads are stock they are a traditional D-port head. If that's the case then Fel-Pro 1406 gaskets will work just fine as long as you retorque the header/manifold bolts after a few heat cycles.

 

It's just the opposite of what the engine/header needs. But I appreciate the effort just the same. At 1.63 width the gasket is paper thin at the flange edge. This is why the oval port gaskets are such a great fit. Worth a look anyway!
Thanks.
