NOS GM BBC 2.19/1.88 Racing Valves, 340286 / 340287
 

Sold! Thanks sYc!

Never seen a set of these before - the intake is Titanium and the exhaust is stainless with a hollow stem. Pretty high tech stuff to say the least. Thanks to Larry in Tucson who was able to ID these for me and post a snip from the GM parts catalog. I have all 16 valves.

I'm pricing these at $1000 which is the going rate for a set of 8 Titanium intake valves alone, so I think it is pretty fair.

These are in excellent unused condition - the only the issue is some surface corrosion on a few of the valve tips, which are hardened steel.
