Wilwood / CNC clutch reliability

I'm looking at converting my Ford 302/T-18 combo to a hydraulic clutch and have a couple questions.

How is the reliablity of Wilwood and CNC pull type slaves? Is one better than the other? Is the CNC push type slave good?

Both of these slaves use a 7/8" bore, Wilwood offers a 3/4" clutch master cylinder. Is this master large enough to disengage the clutch?

This rig sees some street time (to and from trails, up to 100 miles per trip), and tough trails. I need a reliable clutch setup, I'd like to hear people's experiences.

I have been running a willwood pull type for 4 years now. The only problem I have found is that they didn't locktite the piston to the rod and it started to loosen up on me (did it on 2 friends race rigs too). After I pulled it appart and locktited it it worked great.

3/4" master cylinder is what they recomend...I have been using a 5/8" factory one and it is just bairly enough for my sm465...

I run a Wilwood 3/4 master and a CNC push slave and it works great. When I was first making my system I used a 3 finger pressure plate (I already had it with my engine) and it was a little tough to get the clutch to disenguage with the hydraulics. I traded up for the multi finger pressure plate and it was alot easier to press the pedal and disenguage the clutch.

I had two Wilwood slaves come unscrewed. I called them and they told me they were unaware of any problem with their slave. I tried Locktite after thoroughly cleaning the threads and it came apart again. I made the fix permanent with a roll-pin.
