Infusing grid cut foam

Hello, I’ve infused a few parts before but never with grid cut , how would you set up a resin break if your feed lines surrounded the flat panel and vac in the middle?

I’m trying to get ready to do some flat foam panels that are about 14’ long by 24" grid cut one side and perforated so would like to do both sides at once

I’ve done infusions before with flow media but never with grid cut seams to me resin would just race right to the vac port?

Thanks
edit , i guess its called groove cut not grid cut
