I don't think you stand much chance undoing/removing them.I've only done it once and that was by setting the block up on the milling machine,machining the head off then carefully drilling the threaded part out and loosening the bit left with heat and penetrant.
Then had to make the replacement plugs,I think 1 1/4 x16 I think.
The worst part for silting up is between the cylinder core and the tappet chest which is impossible to clear.The only time you can see how bad it is blocked is when you cut the block up.
Someone has suggested molassis previously ?
