Basically, the phenolic spacers keep the temp of the upper intake manifold down, but MORE importantly, the increase the volume of the plenum, to the size of the F-150 4.2L. it also increases the effective runner length, boosting torque.

Flex (a moderator here) used to make them, until he took over a home building/improvement business -no time anymore.

There's another sixer who's making 1/2" spacers, but I don't know him . . ..

You could always make your own. The last time I checked, 3/4" sheets were selling for around $20. but they go through cutters pretty fast, and you need a mask to work with the material.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
