67 GTX 440 HP Manifold heat riser Source ?

[clemul]

Hi,

I need the thermal spring and anti rattle spring or rebuild kit for a 67 440 HP manifold to get my car back in optimum operation..Can anyone direct me to a source or have extra's that they want to sell? If unavailable is there any thermal springs from other applications (slant 6, 318, 340, 383, 440 non HP) that can be made to work?
Can someone also recommend the best brand exhaust gaskets I can use on my 440 engine? Thanks for any and all help

Can't help on the heat riser valve eqiupment but on the manifold gaskets, I guess you know that the factory did not install gaskets. I would use a thin coat of the red, high-temp RTV. If a manifold is leaking badly it may need to be lightly resurfaced to true it up. If you are determined to use gaskets then the copper metal gaskets are the longest lived.
