he'd probably have the head work done by a shop, i didnt machine my head on my first motor, i just changed the stem seals. I dont burn a drop of oil at 55k+ since rebuild
notes: honda motors last as long as they are taken care of

he has a SOHC VTEC, that means that he has
lost motion assemblies pushing up on the rocker ramp assembly when VTEC is active, per 2 valves. floating the valves is more common on hydraulic lifter's, like you mentioned earlier. so he is more likely to pop a retainer due to the rpms we are talking about here. my cams spin at nearly 16k rpms each when i am revlimiting at 8000 in a 2.2 liter. my valvetrain is designed for high rpm operation and annoying as it may be sometimes, god help you if your next to me on the highway.
this is the difference between SOHC and DOHC VTEC motors
power.
by adding compression you are getting more HP/Liter, but the SOHC head can only flow so much.

it does. :bandito:
