yeah that^
I was very good about OEM only on my motor rebuild when deeper in there but this is a small enough job that I didnt mind comparing a Felpro gasket to OE(also OE was a week out and Felpro was same day) and wouldnt be a big deal to do-over being that i already did it over once since the rebuild(for a vac leak) and im getting pretty good at it. Very little difference in the 2, Felpro seemed to be the same hardness and hasn't leaked since
I didnt replace my plenum and TB metal gaskets as they were in great shape already but that may not be your case, mine had about 10k on em. you can usually clean them up pretty well.
