I have an ls vtec in my car. The car smokes in high rpms and especially when v tec opens up. Its a blue smoke and it burns oil. I did a compression test and it came out 190 across the board so I figured I would replace the valve seals and head gasket which I did. The car still smokes. It has Oem p30 pistons and everything else in the block is stock. It has a b16a2 head. If anyone has input that would be great.

Check your piston rings, that may be the issue of the oil burning.

TRQLESS

You should have done a leakdown test after the compression. That will tell you the condition of the rings.

Its got to be the rings

J90lude

Agreed

That will tell you the sealing ability of the rings, not their oil control ability.

Stinkybean

Would bad oil control rings affect the compression?

Fabrik8

Generally no, which is why a compression test won't necessarily tell you anything about oil consumption. If you have poor compression you'll often have oil consumption, but you can have oil consumption without poor compression. The relationship between the rings and bore is different for oil control than for compression.

Well what do you think it could be? Just did another compression test and came out as 210 across all 4 cylinders. That's after the head was milled and valve seals were replaced. The car still smokes and burns oil.

You're not listening to what I'm saying. You've replaced the valve seals, and the compression looks fine. The compression doesn't tell you about the oil control capability of the rings, so it stands to reason that the rings could be the problem.
