Blown alcohol small block?

No Teflon lines in my system. I use about 1 gallon of gas a pass and adding fuel each round is the only maintenance I do on race day. Most four day race weekends I never even remove the hood. I at one time (over 6 years ago) said I will never run alcohol. I hate the smell in tight spots. I also like the sound of mufflers on my car so it was a win win running them out to the side. I bought the tubbing for Summit and welded it up myself.
I have not yet decided what fuel I will run, but I have put the proper fuel system in place to run alcohol just in case.
I installed this 2Lb check valve into my intake and pieced together a primer starting system using a jaz junior dragster fuel cell.
The primer fuel pump that Rons uses is available online and I have one of those.see pic of check valve. I just need to decide on a carburetor fuel specific.
Do you do anything specific for winter storage like wd40 the cylinders or run the motor on gas to get all the alcohol out of the system?
