Champion R15B rebuild

Hoping old red will chime in. My speedaire 80 gal tank with the Champion R15B pump (2 stage) is taking a bit longer to pump up these days (7-10 min), and can't seem to keep up with my DA. (The pump is rated at 16.9 cfm @ 90psi, I believe) Anyway, I found a few suppliers for rebuild kits

I guess my question would be which kit would be best, and are there any pitfalls in the rebuild before I get elbow deep in it. I see these pumps go for $1,200 & up, so I don't have any problem throwing $100 in it. I just don't want to go too deep, or not deep enough.

Well, here's what I found. The head was leaking on the output side. The threads on that side pulled out. Got a Heli-coil kit and temporarily fixed. It pumps up in 6-7 minutes, and is keeping up nicely with the DA. There was oil spitting where the leak was, so I'm pretty sure I need rings. While out shopping for sub-$10 wash thinner, my local autoparts store carries Champion compressors, and have the rebuild kits in stock. I did, thankfully, find out that they have new & old R15B rebuild kits. I definitely have an old one built in the early 70's. I also got some all thread, and am going to stud the ouput portion of the head, so I can thread lock the studs in.

I have it under control, but if anyone has any experience rebuilding Champion compressors, please chime in.
