Burning oil after head rebuild

Hello all! This is my first post but I've been lurking the forums here for about 8 months after I purchased a 1995 geo metro (3 banger with 195k). This is the first car I've ever really worked on and thanks to this community it's made jumping in incredibly easy so I have you to thank for that! On to the bad news....

So after it running poorly I decided to do a compression check and the numbers were (from 1 to 3) 20, 80,90. According to the forums this was more than likely a burnt exhuast valve so I decided to pull the head and rebuild it. The #1 had a pretty decent hole in the exhaust valve, and all the other valves were intact but in poor shape. I replaced all the intake and exhaust valves and valve seals and did a leak check with rubbing alcohol and it looked like it was all sealed up. I then cleaned up the top of the block and the bottom of the head so I could put the new head gasket on ect...

For the installation I had my haynes manual out and made sure everything was installed/torqued to the correct spec and proceeded to put the head back on. After it was completely assembled I added all the fluids and cranked it up, and burped the coolant system. It was running fine, but was smoking like crazy. First I thought it was just residual coolant/oil in the exhaust but after a few days of driving it wasn't getting any better. I decided to pull off the headers and see it smoke would come directly out of the head to cancel out anything in the exhuast/cat, and now I'm kinda stumped
Here are some things that the forum suggest that I've already tried/accomplished:

Used a fel-pro gasket (with copper spray)

Made sure the oil valve was in the block

Ran with the radiator cap off to check for bubbles ( there weren't any that I could see)

Did not see any oil in the air filter and pcv valve is brand new and still clean

No coolant in the oil

There IS oil on the spark plus

If any of you have any suggestions or advise I would be greatly appreciative!

I did the same thing years ago on a 96 3 cyl. I didn't see smoke but the motor was using crazy amounts of oil. With the rebuild head you are pushing the oil past the rings and burning through the exhaust. (The oil was burning and depositing all over the inside of the motor)
Do you have a catalytic converter on your car? If not that may be why you are seeing the smoke. I would finish the job and do the bottom end. Rings, rod bearings, oil pump...I did mine with the motor still in the car.

At 200K miles your rings are certainly worn out, cylinders might be worn oval. Rings and hone at least, best solution would be a bore job and new pistons.

Thanks for the fast replies! I currently have MMO soaking the pistons and if that doesn't help I'm gonna do the bottom end in a few weeks, probably get the head milled too with new valve guides just in case. Anyone been able to get ahold of 3tech lately? Also there is GeoJeff that does heads but I haven't seen any reviews on those but he seems to know what he's doing

It's usually cheaper to buy one of the rebuilt heads off eBay than to get yours rebuilt especially if it needs new valve guides
I have bought about 6 from this place and they seem to do good work. They also sell them without cams for a little cheaper

Ok so GeoJeff is definitely off the table......as far as the ebay heads I did some research a couple weeks ago and there is no place in in Spokane washing called northwest heads, turns out it's a guy in his garage ( not that there's anything wrong with that) and he's impossible to get a hold of if you have a problem. Apparently actual machine shops in Spokane get calls from people with complaints thinking they are the guy on eBay.

You do have to watch out, geo Jeff is running a Craigslist ad with heads for sale using the same pic as nw cylinder heads that he lifted from their ad. I had to work on a car he "fixed". Most of it was screwed up and had to replace the head with one from eBay seller. Have bought at least 6 and none have failed yet
