hey guys i'm new to this forum so i'm still trying to find where to post but it looks like you guys are having similar problems, i have a bit newer motor, its a 250 in my 78 chevy longbed, but i think its similar, i have an offenhauser manifold w/ a holley four barrel, i got a kit that includes a plate w/ a place to hook up the heater kit on the bottom of the manifold, i set it all up today, mine is a bit newer but it had an extra nipple under the thermostat so i went from there to the manifold out to a T i put in one of the heater hoses, seems like it should work but now my manifold is leaking, not around that part, but in the front and rear of it there are what seems to be 2 plugs?? not sure what they are, round holes in the manifold w/ something pluging it, its leaking out of there, leaking like crazy, anyone familiar w/ these manifolds? thanks
