There are 2 VR1 oil the one for flat tappet engine says not street legal and is hard to find.
Our street engines we build we have been using the http://www.cen-pe-co.com/ 15/40 which has 1582 in zinc and thier 20/50 has 2300 PPM of zinc and no problems to date,
Your newer oils have alot of detergent in them which offsets the zinc and kills the effect of what little zinc is in there.
Once our circle track engines are broke in we have them run the AMSOIL 15/50 which has 1800 PPM of zinc and will stand up to 500 degrees temp before breaking down.
We have used this oil for years with zero problems

Run what you want but this info should be on the sticky at the top of the page.
Here are all the valvoline tests I can find anywhere. They have a VR1 oil and a VRI oil "not for street use" so look at the label carefully. They also have a synthetic and a conventional. They also have a 10W-30 and a 20W-30. All VR1s are not the same and none of the test results are close to advertised.

I'm o.k. one 4 oz. bottle contains the correct amount of zinc and phosporus. Here is a quote from the source.
ZDDPlus contains the proper amount of ZDDP to give at least 0.18% zinc and 0.13% phosphorus level when a single 4 ounce bottle is added to a 5-quart oil change. This level of zinc and phosphorus is the level designed into pre-OBDII oils. Using ZDDPlus affords you total control over the choice of oil brand and viscosity, ensuring the protection of your solid lifter motor.

From Duke Williams paper:
"From the 1950s to the early 2000s many engine oils were dual-rated, carrying both the then current compression and spark ignition engine service categories, with the primary category listed first, and the typical level of ZDDP concentration based on the mass fraction of phosphorous (symbol “P” on the Periodic Chart of Elements) evolved to about 0.12%, which can also be expressed as 1200 ppm (parts per million). Over the years this level has proved to be ideal for sliding surface protection. Less can allow more rapid sliding surface wear, but too much can have negative effects. More is not necessarily better!"
