Not in this case...

 

They may not make them anymore, but there are still places selling them new.

It's pretty tough to find the intake seals these days and the intake manifolds are getting a little rare.
I recently had to send one out for repair because I could not find a replacement.
Overall, I kind'a like the heads.

 

I have a 1995 89" stroker with HD heads ported to match an Edelbrock manifold.
I had to remove the rear head and I reused the manifold gaskets.
I haven't had any leakage problems.
