btw fwiw, practically all or most of the top running NHRA Super Stock engines, have devcon or a similar epoxy inside the intake ports. they have to, in order to move the port volume around and stay within rules, while straightening the port and gaining some flow. that's one of the tricks they use to get 350" SBC engines with a Qjet to make 660HP. it won't fall out if done right.
