IML: Further on the Unleaded gas effects discussion of last month

["Dick Benjamin" <dickb@xxxxxxxxx>]

A couple of people asked about valve seat modifications to combat valve
recession.   Here are a couple of pictures of the heads for my 68 after
inserting the hardened valve seats in the exhaust valves.  All the valves
are new and shiny here, so the seats are a little hard to see, but if you
look closely at the exhaust valves (the smaller valves), you'll see a bright
ring around them; these are the inserts.

I apologize for the black paint - I promise I will paint them the right
color before I install them!
