another cam question? Comp Cams

[turbophein]

so i spent a couple hours pulling out what i was told to be FP1 cams to install the cams i picked not long ago that i think are FP2 cams.

after pulling them out last night, i can't find any info on them from the numbers?

XE250HR 108* uj5180
XE251HR 106* uk 1066-04


what i am installing, along with BC springs and retainers(should be FP2's)

101-201-8I
101-202-8E

after a little goggling this page pops up but i can't find any info on these numbers. anyone heard of these cams?

Well the XE251HR works on the comp website search. But no info for it.

The XE250HR, shows no results, so you may want to contact Comp cams and see what they have to say, it could be an old grind not used anymore.

there are 2 different xe251HR's on the comp website though, there is a stage 1 (101100) or the am you just posted (101104) that is what is confusing. although my car only made real power above 5kRPM. none of my previous cars kicked in on the powerband like that and i had a few different HKS combos, this is almost like (i don't want to say it) a VTEC when it kicks in at 5k. can i measure the lobes? i am going to be selling these here shortly, i don't want to misrepresent them.
