This is a great idea! The shop looks great and I wish you much success.
I'm curious on your 066/660 exchange program how you ensure that the same cylinder going out is the same coming in. My understanding is that there are several different cylinders, and since the port timing can very greatly, some are much more desirable than others.
Thanks

when porting you are changing any cylinders port dimensions and timing to get the max workable level out of it. ou just go about each one as needed but the result will be the same. if someone wants there own cylinder back instead of an exchange it will just take a few days longer.
