I'd have to say it's still the intake . I dont think the valve seals went south or stem to guide clearance suddenly became too much. A possibility would be an oil ring fubared but k.i.s.s. the worsenening under increasing vac in hg points to the intake. The oil has to be getting sucked into the intake tract somehow.

The old intake didn't look bad, but replaced it with the Mr Gasket better one. If the valve seals were bad wouldn't it smoke at startup? They are Mopar heads. No PCV valve. Seems to be a little oil in the plug wells, but the #2 and #4 plug looked like they were "dipped" in oil! I did have the intake valves replaced also. Did not replace the seals, he told me they were good.
Thanks, Mark
Do you have the compression washers on the spark plugs? if so this very well may be your issue, if plugs currently or in the past were installed with the compression washers, the HEMI plug tube has been damaged/distorted and oil is entering the cylinder, seen it before, common mistake, if this is the cause, replace the tubes, and remove the compression washers from the spark plugs, the HEMI tube is your compression "washer"

Are the studs into the heads sealed properly?

I used ARP thread sealant on all studs.

The washers were on there previously, not now.

Well chances are the tube bottoms are distorted by the compression washers being on the plugs, so I'd replace the tubes, don't bother trying to reshape the tube base, and install the plugs (new set) without the compression washers, fire it up, clean it out and see if the smoking has stopped, I've seen this very issue over the decades on quite a few HEMIs, common mistake

Here's where I stand, I'm pretty sure it's not the intake gasket. Replaced it twice and it looked like it was sealing. With the blower and intake off, the top of #4 valve looks considerably cleaner than the others. I think this also rules out the spark plug tubes. That only leaves valve seal or head bolt. There doesn't seem to be any oil where the head bolt goes into the intake port. So I'm leaning toward valve seal. If I get the spring compressor from Mancini or Detroit City, how much of a pain is this to do with the heads on?
When does this car start to become fun?
Once I took off all the race stuff off my street car, it became fun and way faster!. I know you can't do that with a blower very easy, but that's what I did 10 years ago with my 340 and have really enjoyed it in the last 10 years. It's not stock by any means, just close enough to be reliable and it runs really well with it's 10.5-1 KB pistons, single plane intake and Eddie heads.
Are going to do a leak down before taking anything apart this time, so you know whats wrong?

Prob will do a compression test this weekend. Valve seals are cheap enough, I just hate to spend $200 for the tool to compress the springs and find out that wasn't the problem.

You might be able to rent one for cheap (an ad on CL could get a response). In addition not sure if a leakdown could pinpoint fubared oil rings or just the compression rings but I would seriously consider locating one/doing a leakdown before tearing it down

You need to do a leak down to learn any thing, different than compression test.
Spring compressor for use on the head can be fabricated pretty easy at home with no welder in some cases.
Who out there has made there own to post a picture of it. I have made a couple over the years but I used a welder.
Please post your pictures of your homemade compressor to help this guy out.
