Custom cam grind question

What can you change exactly to make it custom? I assume anything, but don't know. I will be calling Hughes tomorrow, but was thinking about it at the moment.

I have decided on one of their cams, probably the whiplash, but I hope to customize it for the following reasons:

1. 110-112 lobe centers (seeking a bit more vacuum and a tad bit less lope)
2. Maintain or even improve the 30deg ABDC intake valve closing hard point (seeking to improve dynamic CR)

So just wondering what the limitations are for a custom grind. Below are the specs for the (2) cams I am considering as a starting point to best alter to get to where I want, which is immediate torque with best dynamic CR.

Cam #1 Whiplash:
.485/ .518 lift on 109 lobe centers (104 deg intake CL)
213 / 236 duration
Idle - 4200 rpm sweet spot
IVC is 30.5 deg ABDC (lower the better for raising DCR)

Cam #2 HEH1019AL:
.461 / .489 on 112 lobe centers (109 deg intake CL)
210 / 219 duration
Idle - 4600 rpm sweet spot
IVC is 34 deg ABDC


Thanks
