Angry Help Big trouble?

When my 82 12a gets up to temp steam strarts coming out of my motor on the exhaust side? I live in the Northeast and had the anti-freeze set for about 10 below zero, it's not the thermostat housing new gasket and thermostat I put a new radiator cap on also , I can't see where it coming from.

I had performance issues slow RPM's and poor perfomance overall, so I swapped the fuel filter and fuel pump, plugs wires dizzy and it still didn't help? I worked on it Sunday when I noticed the steam coming out from under my hood, When I changed the thermostat some coolant leaked down the block but I it ran it for awhile and it didn't get any better. HELP

There are two o rings between the intake and the block. These become deformed and brittle with age, and can start to leak. That might be your issue...

Thanks I have the parts ordered and I'm hoping that this is it, I really like my Rex and I'm new to this, rebuliding my 12a was not in my plans right, I may have pulled the trigger a little quick and didn't do my search like I was suppose to, so thanks again for you reply
