Two of those Kits use SE257 cams.

One of those Kits uses SE211 cams

Both Stroker Kits, bumping the 88" to 103", use the SE260 cams

Ooops, I just noticed that typo....

It should have read that, "four of the stage Kits used SE203 cams."

Do you mean the 2001 Parts & Accessory Catalog Stage kits offered....?

Per my 2001 Harley Parts & Accessory Catalog, there are :

Two Stage I kits, neither with new cams.
Note: One of the Stage I kits is actually a big bore kit (1550), but without new cams. So I guess that's why they call it a Stage I...

Two Stage II kits, both with SE203 cams

Two Stage III kits, both with SE203 cams

Two Stage IV kits, one with SE257 & the other with SE258 cams

There were no Stroker Kits in that catalog.

I got that manual on eBay...

Every time a buy a bike, I try to purchase the Factory Service Manual, Electrical Diagnostic Manual, Parts Catalog, and a Parts & Accessories catalog if I can, for that year/model.

I currently own 4 Harleys, but I have amassed a good reference library over the years...

There is currently one for sale:

In 2005, I ordered a Stage II BB kit and it included the SE203 cams. I had to order the SE204 cams separately; the dealer would not, maybe could not, substitute the SE204 for the SE203. JMHO but the SE204 having 8* advance ground in was a stronger option than the SE203. The SE204 is a very underrated cam IMHO; great midrange to the rev limiter but static CR should not be more than 9.8 if one lives where summer temps can reach 100*. Choppy idle, obvious that the motor is running a cam; much like the old Duntov cam for SBC hop ups.
