Well that’s the best I can do on this set of heads.

And here I always thought a bigger valve would be a good thing! :lol:
Bigger not necessarily better.
Years ago a friends girlfriend had a friend who was extremely sexy. We all wanted to get nto her pants. Another friend was hung like an ox. One night at the cabaret she picked him. They went to his place and eventually got to removing their clothes. After he removed his s ivies, she took one look and put her clothes back on and said "you are not sticking that thing in me!" The next day guys asked how it went and he told us. I asked "what did you do then stud?" That stuck to him as a nickname for years.
