The shop doing my head work, basically custom made some, from someother they had on hand, after they recut the valve seats.
The new valves are larger than the stock size, needed to cover the ported heads. I dont think they are "special" as in titanium or anything, The springs <(higher lift) and retainers are though. The guy explained to me, that if something happened to the timing belt, it's better for the valve to give than the piston. However _ He assured me I'd have no problem at high pressures, and to keep the valve train up to higher rpms, the hydrolic lash adjusters, are being replaced with manual soild rollers, that you have to take off the valve cover and adjust with an allen wrench when needed. Something about the hydrolic ones,((and the stock springs) not being able to keep up with higher rpms - Where the hydrolic fails to deflate or "pumps up" not letting the vavle fully seat, and the double rollers are supposed to create less heat than the single rollers... I'm not sure thats really of any consequence though.


So anyway - IMO unless you've recut the valve seats, there is no need for new valves. But the springs, retainers, and lash adjusters got to go if you plan on serious HP ans RPMs.

If you need to replace a valve for evil reasons, look here
