Staggering Intake/Exhaust rocker ratio's

[Quick_2s]

I'm trying to wrap my head around the actual numeric effects of this and what it does to the compression, duration and such.

Compression unchanged, opening and closing events relatively unchanged, the lift rate increases as does the total lift.

That's one of the nice things about XL's..... endless possibilities on cam combinations

So basically it opens faster and farther. I have .647 cams with a 650 max lift set of heads, would 1.75"s push me outside of my tolerances?

if my calculations are correct that would put you at .705 lift  thanks pete

Thanks, but it seems that's out of the range for my springs I guess.
