Water neck gasket yes or no?

[Bb70charger500]

My auto zone sells a rubber gasket it's like $11.00 but I've never had any problems out of them I've been using them for 10 years now I actually need another for my 340 I'll see if I can get the part number for both small and big block

Please take a minute to email Mancini and let them know about the problem. Every future buyer of that water outlet will thank you for not having to do the same thing. If they don't know about the problem they can't rectify it.

Elongated holes in Mancini neck, used Felpro gasket and right stuff on outlet and manifold, let it sit 24 hours and took it for 15 mile ride, so far so good, no leaks.
