Air filter/cleaner question

[71shortygray]

I have a 71 P10 with an 250 inline 6. It originally came with an offset air cleaner that had a riser/connector tube that went from the carb to air filter house. A hose would run from the side of that connector and into the side of the valve cover (see pic of an example).

Mine is missing the offset air cleaner and connector but still has the hose coming out of the valve cover. So my question is would there be any issues with just taking that hose off and plugging the hole in the valve cover and then putting smaller air cleaner? Found one for that is 6" x 2.5" that will fit the space and carb.

Thanks!
