I see that FelPro sells a neoprene seal for the V6s BS40613. Either way, make sure to polish the knurls down or it can chew the edge off of the neoprene seal (that much I do remember).

231 has 2.500 main journal diameter. 460 ford and 350 buick both have 3.000 main journal diameter. Fel pro bs40032 is the one to use.
