"Would you install a 2.15" intake valve?" Sure for racing,, w/an engine that you know will come apart shortly.

The reference to installing that large a valve in these heads was only made, because in another post about head work, someone cautioned the person that installing intake valves larger than 1.84 would likely strike water. I was pointing out that we frequently and successfully installed valves that large and never hit water, and was just clarifying that point, and not suggesting that the user attempt to put those large a valves in his head, and even said that in the open remarks originally.
