One thing I forgot to mention in my first post regarding those heads is that they have 1.72" intake valves. I don't know of any 350's with the small intake except a set of truck heads that had 11/32"diameter intake valve stems and 3/8"exhaust stems.That must have been an attempt to stop the excessive valve guide wear caused by the lower lead content of the fuels back then.The 1970's sure were a mess as to the effects of things on the automotive industry.
