Replace the bleeder valve with a suitable zerk, (the 356 Porsches are 10mmX1.00 pitch...I cannot believe ATe made many different sizes here, but check), and then use a good, manual grease gun to expand and free the parts.  Do this in a heavy, clear plastic bag to prevent the parts from leaving town...and wear safety glasses.

Yes, you did mention this method a few weeks ago. It's probably a 
good choice for Dennis. M10 x 1 would be the inlet ports; the bleed 
valves are M6 x 1.

Our MCs have 3/4" bores, but the rear cylinders are 7/8" in all the 
later years. Both are actual inch dimensions, although the disk 
calipers are metric.

I'll have to look into the Permatex lube. I'm not familiar with that 
and I'm always looking for better products as brake lubes. This is a 
non-petroleum product, right? What does it look and feel like?
