Jim,
I have been using fire rings on 928 blocks for some time.....but never made of steel due to the CTE issues at elevated temps. On the first engines I used natice 390, but I can no longer find the old RR castings for material supply...
Have you heated the block to 200-220 F with the rings on and if so, have you measured the taper in the bores?
Mahle Ferroprint is looking like a good material for our applications...looking forward to the results.
Great project, looks like someone is having fun! Enjoy!
