RE: coupla MC motor questinons..

Except that you now change the forces acting on the cam lobes and when
stiffer springs are used - to handle higher rpms that are usually the
dwelling place of extra ponies - you end up with a highly stressed valve
train more likely to suffer a catastrophic failure at a most inopportune

as Scott J. would say... just my .02

By changing the cam's base circle and adding lash caps to the top of the
valves to make up the difference ... it's done all the time (although using
valves with longer stems is usually the preferred way to go).
