If a grinder is using the same lobe series for both intake and exhaust the exhaust will show more lift with more duration
if the grinder developed separate lobes for the exhaust- which is currently the way to do it
then you may end up with a lobe that is a little longer but a little less lift or ???
depends on your head flows, open or closed exhaust, lots of things
SSG do not try and pick lSA yourself
it is the result of what your lobes are NOT an input
get the right timing and lobes to match the timing and lsa magically appears
seat timing is valve motion- start there and work back through your port flows to the cam
YR think about rocker arm specialists
I've had good results with their bushings, shafts, etc
agree on the cup adjusters
we may differ on oil through your new as big as you can fit pushrods
but will your oil squirts work?
