Quick Header Question

[Leadbut]

I have a set of Hooker Super Comp Headers 7104HKR.
I recently installed later model heads (3196291-c ) while rebuilding my 1969 390.

Can I use these headers with the new heads?
If So what gasket do I use?

are the old heads dog leg ports if so then you should be able to.

The old heads were the stock square ports.

The new heads are dog leg ports.

[ironman_gq]

gonna need new headers

Guess existing headers are also rectangular port ?
If so, yeah, would want new doglog port headers for dogleg heads.
Many opinions on gaskets, have had good luck with Mr. Gasket #5950.
Some use only red hi-temp silicone and no gasket.
Others the gaskets that come in the FelPro engine gasket set.
