replaced valve stem oil seals ... Still smoking ! 273 HP

I had a bad issue with oil burning and smoking out the pipes ......So I replaced the valve guide seals on the 273 hp charger , the oil seals were desinagrated as you can see in the pic. and found all these pieces laying under the valve train gear. . alying on the head .
Well , I thought this was going to solve the smoking issues but it is still smoking pretty bad when I get on it hard..

the engine does not have any internal blow by issues

compression check with gauge is 180# -182# on all cyls. hot and carb wide open .

Plugs look great nothing fouled anywhere. n9y champions.

checked to see if intake manifold might have been sucking air around the ports and appears to be fine also. plugged one side of valve cover and did a air flow test and vacumn check to see any air was being pulled thru the breathers on the covers . (pvc plugged) all looks good there.

This 273 sat for many years .. A mechanic told me it may have sticking rings and I should try a pint of that mystery marvel oil and run it thru for a short time without beating on it to see if would free up sticking rings,

Has anyone ever heard of this to try?

thanks for any inputs on this issue .
