intake manifold problem..

Hey guys,
I have an issue with the carb manifold I'm using, the Edelbrock 2121. My old GT40 intake had a channel for water at the back of the manifold, whereas the 2121 does not! Would this be an issue with my cooling? I really don't think so but I wanted some opinions. Also, the 1250 felpros I have have provisions for the rear water jackets. is it ok if I just seal them with silicone as usual and call it a day? Thanks!

You should be fine. Every edelbrock intake I have installed worked that way. The Capri and my 67 both no longer have the rear water crossover.

What does the rear water crossover suppossed to do? If it came that way from the factory, they had to put it there for a reason, right?

That's what I think. But really, it just flows right over. At least the front has purpose with the sensor bung/heater hose inlet and the thermostat. Hell, if the Cleveland family does it, why can't the windsors!?

I even asked the machine shop owner that was building my 351W at the time about it. He said it wasn't needed and I haven't had any heating problems since running it.
