I feel The hardest part is... and getting the oxidation off...
scream, had the nephew keep bringing me parts to build a chopper. I tried in-house up to cutting the seats and proper guide bore tool. In other words, I used the pre-drill and honed the rest and smoke'em. Feel wise I'll know when to stop. Final bore tool was $400 fuck that.
But the point was, don't punch out the guides with carbon or it ruins the bore for the next set and vinny did the trick. AS IF steamed cleaned. Do this. Just dip the exhaust valve in a cut down plastic drinking bottle. Just up to the tulip so some carbon is still on and test that way. Say pull it up in 24h and finger push it. Dip it for another day and you'll see how easy carbon comes off.
Like I said, instant polish as soon as I submerged the S&S in the vinny alone. I now add peroxide. Again, old lady walked away from a pan that she had made apple sauce from scratch and covered the whole pan black. Tried adding peroxide as an experiment, because last time, just vinny straight did not cut the first burnt pan. W/peroxide it wiped off. Go 50/50 if you want.
Buddy had a carb sitting for years and I then tried NAPA's carb dip for 12 bucks. Will never vinny up if I can use the carb dip all fresh and new. Watered it off, what a beautiful job. Like 3 bucks at costco for a gallon of vinny is it? Might need a few cans of carb dip and let it eat the carbon and oxy that way. Then you have cans of toxic around. Vinny down the drain and let it sit and eat that shit.
You have nothing to lose is 5% acid on that valve face if you want to make a case for VinPx mix.
As far as fin, grime, dirt released from both liquids, say we add baking soda as the last chemical to react and once the bubbles end, probably took care of the oxy no doubt if not the liquids. Ah, you can wash it off and see how clean it is. Then if not, dip and soda for the finalize. Still only 3 dollars to lose, The other two are around the house, yes?

So say out in the garage I meguyveer and veer over to point A and tie the rope. Walk to point B and tie that off. I can stand on the rope is the integrity of A and B. When she's not looking, take the fattest towel so the rope even makes dragging the fin tighter.
Get it so far? Then pour the polish at the V at the peak of the rope, but down the sides, right? You are going to zip back and forth, face of the fin is going to heat up all along that fin to polish out some heat to move shit off the finish. The fuck if I'm going to eat and sneeze fuzz off my dremel drill big or small. I rather... dental floss my cylinder barrel and head is more the zip-zip down the rope and back.
Okay, she caught you. Too short are the felt-free's to drape over the line and what a short run no way. 4 runs down the hallway and and back and you're done with a fin. Towels too short, you use two sheets and Popeye the rope with some spinach so it spreads out against the fins, right?
