HELP! Smoking Car

[MNNI Z32]

I recently bought a 300zx twin turbo, shortly after purchasing i had a shop replace the timing belt and the one of the exhaust valve heads (with used head in good shape). The heads were sent into a machince shop and inspected to make sure tolerances were OK. Then it was sealed back up (all new gaskets, from the bottom of the block up) and suppose to be good to go. I drive it home about one mile, everything looks good, and then i come to a stop and it smokes quite heavily after its been under a load and slowing down.

So i call the shop back up, they take it for a day to inspected it. After the day they tell me its the PCV valves and doing a PCV delete will help. I did the PCV delete and ran pop charger filters on the valve cover "tower" hoses today only now the car smokes from the exhaust and the pop chargers!lol Im sure i look like Cheech and Chong every time i roll up to a stop sign. Please help!

Question is what color is the smoke? And running breathers is all fine an dandy, but deff would run a catch can, instead of just the breathers. Because all that is basically doing is venting the positive pressures and venting it to atmosphere. And could be the oil saturating the filters and dripping on the exhaust

+1 to all, very suspicious of the PCV delete which has to be correctly done taking into account the mentioned crankcase oil pressure.
