Sure, a better bet though would be Na filled 964 intakes, light and heat effective.
Most exhaust valves are 2 part anway, w/ a magnetic ss alloy for the stem and a non magnetic heat resistant ss alloy head welded on
Mahle won an award in 2004 for their hollow, nickle alloy valves. but they are just going into production now and Toyota has a trick Ti mmc alloy that they use.
