A metal coffee can and mineral spirits worked well on my 383 Mag in 1991. I used carb cleaner on my Ironhead Harley and a toothbrush... in my living room. Forged Manley Pistons.. runs in the 7s in the 8 th... but the smell in the living room....
Using gasoline is a good way to injure someone. Fuel is for combustion..( and is poison) solvents are for cleaning ( and still flammable)
You wouldn't (shouldn't) use a screw driver for a chisel. The proper tool always works better.
Are the pistons still in the holes ? If so make sure what ever you use gets rinsed down and out of the oil pan.

I just cleaned mine with a small wire wheel on drill, then steel wool coarse and fine spraying brake cleaner until I thought it was good enough.
Use carb cleaner, kerosene, or simple green then Dawn dish washing detergent and hot water, blow dry. A toothbrush or plastic bristle scrub brush works good.

Is the shortblock assembled?
I just did this in an assembled 400 shortblock using a 50/50 acetone-transmission fluid mix and it worked great with just a rag to wipe it off.

Those 10.5/1 273 slugs are quite handsome!

Trim removal tool...the plastic kind to keep from gouging the cyl wall if the engine is still together.
Otherwise be careful and use a small putty knife.

I remember looking a set on rods pulled from a 64 or 65. I dont remember the valve reliefs...the wedgy sloped head I do remember..and a letter. Are those stock, modified or after market?

Carb cleaner and a fine brass wire wheel. I tried using a toothbrush once, but couldn't get the taste out of my mouth for weeks afterwards...

I just remember a valve troff.
Not individually cut, just a troff like the 1st round of kb356's were but are now individually fly cut.
Haven't seen anything like that. All the aftermarket HP273 pistons look like the oem ones that I have seen but that has been in the last 10 years. Dould have been a old TRW or Jahns or something like that. Never say never.
66 or 67 Stock 273 Commando
Old TRWs look the same, only forged. Same individual valve pockets.
Propane torch and a brass wire brush. Oven cleaner works and should not damage the piston. If they are out of the engine you can soak them in carb dip. Many ways to skin a cat.
I soak them in solvent then scrap them with a razor blade. then Finish it with emory sloth 80 grit!
Bristle discs.
Been using them forever.
They have various hardness to them.

Yes sir I use them to in the Engine building shop I work in on my days off. They are awesome!
No response from OP. Are the pistons out of the block ? Or what. That would make a big difference on cleaning the pistons.
Out of the block of course!

Pistons are out the block. and yea i know gasloine is flammable thats why im doing this outside
Thanks for all the responses i ended up soaking the pistons in half a gallon of Gasoline mixed with 1 can berrymans fuel injector cleaner. Total cost 5.99 for the berryman fuel cleaner and 2.50 for the half a gallon. Used a wire brush let it sit for an hour. came out pretty good!
