Using 18 degree pistons in a 23 degree block

I have a set of dish pistons that are supposedly for a 18 degree block but can these be used in a 23 degree block? What is the difference other than 5 degrees? There is no valve reliefs and the dish is round.

It is not the block that is 23 degrees it is the head/valve to piston angle. You will have a problem if you need a valve relief because it will be in the wrong spot. But if you do not need the relief you should be OK.
