Default LSK vs LSA lobes

Comp cams asked me which lobes i wanted for my custom 224/230 .598/.598 110lsa cam, LSK lobes or LSA lobes, does anyone know the difference. i believe the LSK lobes came on the XFI cams and the LSA lobes came on the LSR cams. any input would help. my original thread on which cam to get came from here:

I was under the impression the LSK and XFI were 2 different lobe families. Atleast according TSP's website when creating a custom cam they are.

The Torquer V2 uses XER lobes on the both the intake and exhaust. The V3 uses an LSK on the intake and an XER on the exhaust. There are no LSA lobes. LSA = Lobe Separation Angle which is the angle in degrees between the peak lift on the intake and exhaust lobes. XFI lobes fall in betweem XER and LSK lobes with regards to max lift and general harshness on the valvetrain. If you want a standard T2 on a 110 LSA why not just order it from Texas Speed? FYI, PTVC will be fairly tight if you're getting it on a 110.

The prolly meant LSL lobes which are on their LSR cams. Good power and easy on the valvetrain from what I hear. You can even run beehives with them. I might try these when my 402 comes together.

There is no LSA lobe but they might have been asking what Lobe Seperation Angle you wanted your cam cut on...

I would tell Comp what valvetrain parts you're using, and take their recommendation on what lobe to use.
