NOS GM BBC Valve P/Ns

[Kurt S]

Note the intake says titanium, the exhaust is 'hollow stem, light weight'.

----Yes,,, and it also says titanium "alloy". Could it be that it's titanium mixed with other metals? Just askin!......Bill S

Test results:

All valve tips are magnetic.

None of the remaining surface of either intake or exhaust valves is magnetic.

The intake valve is 3.4 oz

The exhaust valve is 4.1 oz

So yes, the intake valves are definitely titanium (with a steel tip)

I believe the pic of the parts listing is from the GM Performance Parts Catalog from 1984.
