Technical EGR Valve

Im curious if anyone knows where i can find the correct EGR valve and mounting bracket for a SBC 350 intake manifold 3997771 or a place i can get the right block off plate. i made one but it doesnt seem to be sealing correctly. the EGR port is the rectangle one with the slope to the mounting hole.

 

3997771 is cast iron used on 190hp 350(L48) & 250hp 350(L82) 73 Corvettes. I've seen both new & used readily available on E-Bay as well as EGR delete kits. I deleted mine and used 3/16" aluminum cut to size in conjunction with a gasket, problem solved.

 

Just "make" a plate, and bolt it on.
That IS the HAMB way...

OR...get a better intake manifold.

this is the best answer so far
