cam specs?

I cant seam to find a list of the current different cams and specs you make for 12valves, i also saw on your forum you were going to make oversized valves too, but couldnt find any real info on them. I was also wondering what the stock rocker arm ratio is on a 12 valve.

I found this in an OLDER post...

181/210 .280/.307 107LSA
183/220 .280/.316 106.5LSA
188/225 .310/.319 108LSA
215/232 .319/339 108LSA
223/232 .370/367 108LSA

This is what i found on your new dyno thread...

181/210
188/220
200/220
232/252

I want to deck my head to protrude the valves alittle, but i dont know how much because i havent brought it in to get looked at and measured. I WONT be touching/decking the block, but i dont know how much to cut them until i measure everything. I also want to keep it streetable, not a daily driver, but if i want to run around, i want to be able too. from what ive read the 188 would probably be best, but what about the 200? what are the down falls, if any?

A quick search yielded:

We also have a few new grinds about to be released
On the rockers, they are made sloppy/uneven from the factory, or differnt models/year 12valves used different lenghts?

As fas as cams go do you have "general" numbers as to how much is "usually" cut from the pistons for the bigger cams?

I can have the entire tops cut off ALOT cheaper then fly cutting, but i dont really want to sacrifice compressiong and driveability that bad.
