Z28_LS-WON(1)

Its a '98 z28 with the perimeter bolts. I put 799 heads on my car and when i looked at the passenger side valve cover it only has one deal to plug the hose to the TB. But on my old valve covers i have 2 connecters on the passenger side valve covers. How should i route the PCV hoses? Just plug one the pcv hoses up?

Thanks! any info is helpful and sorry for any incorrect terminology lol
