burning coolant or oil ! or both !!

[Gordon1987]

Head gasket brand new and head has been torqued properly but as I test drove it white smoke correction extreme white smoke starts pouring out exhaust every 5 min .
HELP !

White smoke is probably coolant. Oil smoke is blue and smells. One way to check is start car and take a cold piece of steel and hold it behind the exhaust pipe so the stuff will condense on it.

Truly white smoke is vaporized coolant. Condensation is slightly grayer.

When you replaced the head gasket did you have the head checked for cracks and surfaced? Did you use new head bolts. If the head was warped or cracked just a new gasket won't help. If you re-used the head bolts they may not be correctly clamping the head.

The machine shop said the head was good. But I did reuse the head bolts with new gasket

The head bolts are stretch to yield types and can't be reused. It can happen, but I've never seen a head come off an engine that didn't need to have at least have a minimum (.005") cut to eliminate warp. And that has been engines that didn't have head gasket problems and just needed a valve job.
