Smoke is every where in the house is there a seal broken?

check for a cracked / broken pipe at the brake master cylinder the squirts fluid on pressure

DOES IT USE OIL? BLUEISH SMOKE? POSSIBLE VALVE SEALS, IF SO YOU CAN REBUILD THE HEADS OVERLAP THE VALVE SEALS, OR NEW HEADS, IF ITS WHITE AND USING COOLANT, GO TO PARTS HOUSE GET A COMBUSTION GASES TESTER AND TEST FOR COMBUSTION GASES IN COOLANT, THAT WOULD BE HEAD GASKETS

Hi Diane
Most common cause of overheating is a gradual loss of coolant from the thermostat housing seal. You need to top up and bleed the system and arrange to have the thermostat housing checked / replaced.

How many miles on engine?. What color smoke? If white clouds of smoke that goes away when it warms up that indicates a possible housing seal. Another symptom would be having to add coolant. view this video -> https://www.youtube.com/watch?v=4H-B1nckyFE

Replace the transmission housing is what I would do.

Get a used pump & do the drain mod &
loctite the new seal in place

Could be the converter hub is not running true
& took out the seal

This widespread problem is the one part no one thinks of: ENGINE VACUUM PUMP.it runs mechanically off camshaft;once seal leaks,oil from camshaft housing enters vac oump and becomes ingested by engine,therefore exiting tailpipe,water accumulation in by product of catalytic converter changing smog/carbon to water/vapor.REPLACE VAC PUMP AND SEAL ,SMOKE WILL STOP!!!!

Too much oil, it maybe burning oil if its blue smoke its an old car engine wear is a high factor. Try a service may help it alot.

color of smoke

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.
