A long time ago, I purchased some heads online. They were bus heads that were supposedly ported to accept 38mm exhaust valves. I got the heads and they were total crap. When I took the springs and valves off, I found that the exhaust ports were completely stock. The valve seat was odd- the base was as narrow as the stock port and it angled out to 38mm so that it could accept a larger valve. Why? Correct me if I am wrong but it seems like if the port is the stock size- a 33mm or 38mm valve would have about the same flow if not less with the larger valve.
Is there something that I am missing or is this as dumb of a head job as Clinton/Lewinski? (I am posting this for educational purposes- I have several usable heads. These are trash as far as I am concerned) Attached image(s)
