Wheel Cylinder Question?

[my68c20]

Hi all I just shortened my driveshaft and have it in now comes the brakes I think the front wheel cylinders are kinda pricey so I am going to try rebuilding them my only concern is breaking the bleaders loose without breaking them off my idea is to submerse them in a cup of PB Blaster or kroil but the rebuild kit says any solvent has to be dot 3 compatible my thinking is if I use brake clean after and blow it off with air it should be ok. What is your opinions will this work or will I need to use heat also? There is no substitute for experience and in this situation I dont have that! Any help would be greatly appreciated! Thanks!
