IIRC, APE Jay posted that Andrews went out of business and APE bought the design for the 8X cams and now sells them as the APE .410 grind. I could be mistaken though
Did a quick search and found the following:

When Andrews got out of the import bike cam business, we purchased the masters for the two most popular ones, the 5X and 8X. Those became our K410 and K435 which are still very popular.

General info found on a Google search:
Both WebCam and MegaCycle offer hardfaced reweld cams. This requires sending your cams to them to be machined to alter the profile. This will cost in excess of $400.
Also, replacing the stock cams typically require that the pistons be replaced also. The stock valve springs in the ZR-7 are the same as the GPz 750 and can handle up to about 0.385" of lift. The lift for the ZR-7 is 0.320" with 270 degrees of duration at zero inches of lift.
Camshaft duration is measured differently depending on the manufacturer. Going from memory here, I believe Webcam measures their duration at .050 of lift while megacycle measures their duration at 0.40 of lift. The primary reason they do this is to prevent an apples to apples comparison with respect to cam shaft duration.
Just to give you an idea where I am at with this, I have a Wiseco 810 kit sitting on my work bench. I also have purchased a set of Yoshimura Stage II camshafts for the GPz 750 and stock GPz 750 cams (which offer 16 degrees more duration and .040 more lift over our stock cams). I also have a set of stock 750 Zephyr cams, which I would use as a core if I decide to go the Megacycle or WebCam route. Both the Yoshimura and GPz 750 cams I have have the smaller exhaust base circle.

Undoubtedly the cheapest option and the easiest to find would be the 83-85 GPz750 cams.
I just noticed that your sig says "Soon to come, Webcams 110", do you already have them or are you sending your cams in?
