Valvoline Restore and Protect for Gen 1 SBC flat tappet?

[66 Chevelle Guy]

I currently run Amsoil 20w-50 ZRod with a Baldwin B6 filter on my roots blown SBC in my Chevelle. I have oil consumption issues and suspect my oil ring lands may need a serious cleaning due to some plugged breathers I was running causing crankase pressure that affected ring sealing. I am considering running the Valvoline Restore and Protect 5w-30 for a while to clean it up but am concerned about possible lifter wear from the Valvoline that has less Zinc to protect my flat tappet solid cam and lifters. My other option would be to pour a can of Seafoam in with my Amsoil. Any input is appreciated.

I'd probably try and find an HPL oil with higher ZDP levels first.

Here's something that works on aircraft engines, probably safe on car engines too:

That's sounds like an extreme flush. I am sure that its effective, but could be diffcult to execute in my hot rod due to the spark plug locations.

Silly question, but. Does it ever get the snot run out of it??? You know at least 6000RPM shifts? Holding it wide open in high gear? Engines like that love to be revved up and used like it was built for.

How many qts per thousand miles is it consuming?

How many qts per thousand miles is it consuming?

1qt in 250 miles so 4 qts in 1,000. Fresh valve seals done last year.

Yes, I have a safe "test area" for WOT stretches.

Do the rocker stud threads extend into the intake ports?

Piston to wall clearance?
Piston material?
Ring gap?
Boost pressure?
How is the crankcase ventilated?

I resealed the rocker studs a few months ago. Engine has 30k miles on it. Four breathers and no pcv. Total Seal rings with TNT top ring hand file gapped per manufacturer recommendations, cant recall what it was. Two of four breathers were restricted so I replaced them with large open element breathers. Boost is irrelevant since oil consumption is happening at cruise while street driving. Piston to wall clearance was correct spec for SRP blower pistons when block was bored. After 30k miles who knows?
