Hi,
I have a 1964 Buick Skylark Conv.
I am rebuilding the engine, and trans.
I noticed that
there are no valve seals on the heads, and no mention of them in my Chassis manual.
Can some one tell me why this is the case?
The factory intended the seals to be used only on the 401 and 425 nailhead engines, which have vertical valves. Dealers were cautioned not to use seals on the 225 and 300. See attached dealer service bulletin 64-174 dated 8/7/64.
