Be sure you know EXACTLY what you're doing or pay a competent shop WITH 4B11 EXPERIENCE to do the job, cams on the X are not a drop-in affair like they are on the previous Evos/4G63 engine. Also, expect at least a few days of downtime while waiting for the proper buckets to be ordered.

i know that any size kelford has a higher lift then to any of its competition companies. if you dont understand that than here you go..... a Kelford 272/272 has a higher lift than a HKS 272/272
for me i dont like being tight with my money and settleing for something i dont actually want. if i cant afford it at the time i wait till i can get what i really want

Check out this huge comparison:
https://www.evolutionm.net/forums/ev...-cam-test.html
Comparing 268/268 and 272/272 doesn't tell the whole story. A GSC cam has a shorter intake lift and a longer exhaust lift than a similar HKS cam, so it's going to have a different effect on your car.
What are you going to be using your car for? DD with occasional track days? Maybe your main focus should be usable mid range power. Drags? Look at some of the cams that affect the top end more, but be prepared to upgrade your valve springs as well. The bigger you go, the more ancillary items will need to be upgraded as well.
I've wondered about the random differences in prices as well... You can spend $250 more for a set of cams that don't get reviewed as well as cams from GSC, so I wonder why anyone does.
