A little more flow ?
For all those running a low intake valve lift, you "might" want to consider a 30 degree seating angle. According to David Vizard, this makes a 2.05" dia. valve flow like a 2.46" dia. valve/45 deg. seat. This usually requires a tighter guide clearance, and possibly a "conformation groove", on top of intake valve,(also reduces reversion). Onward, roverman.
