8-71 alky blower on the street ?

I wouldn't remove the teflon strips. I have a hard anodized case and rotors on my 8-71 with 6 point teflon strips. I think the alky ones run nylatron strips and my even use 18 point strips. Can you check the rotor end clearances to case? Was this blower originally setup for alky?
I say run it as is.
