I believe I've cured it.

I swapped the cam, followers/rockers out today.

I however failed to save the cam tensioner gasket (forgot to remove spring and had to take the tensioner off, wrecked gasket)

It runs so much smoother, and has nearly zero blowby (I did only run it for about a minute until i noticed the oil pouring out of the tensioner area though)

Hopefully when the new gasket gets here and I get the valves adjusted better (i did a very quick dirty adjustment, I'm going to make a set of wrenches to make it easier before I do it properly again)

I'll be sure to update this when I get the new gasket and get a chance to warm the engine up and such as it was always worse when it was warm

One of the rockers had some significant wear on the bottom where it contacts the adjustment nut thingy. looked like it had been bouncing around pretty bad. I'll post some pictures of that as well as the wear on the old cam when I get a chance to work on the car again!

Thanks for all the help!
