It would be something like this:
IOWR_ALTERA_AVALON_PIO_DATA(DATA_OUT_32_BASE , (val_1<<24) | (val_2<<16) (val_3<<8) | val_4 );
But this is very inefficient!
Still better the 4 byte writes.

Thank you very much for the code.
Could you please tell me why it is inefficient? I wanted to do it this way because I could potentially need to send 16 alt_u8 integers at a time for another calculation. Instead of having 16 8-bit PIOs, I wanted 4 32-bit ones just to make things less cumbersome in SOPC builder. So do you think I should keep my 16 separate 8-bit PIOs or is there a better way to send these integers?
