Good luck on the hunt. I spent quite a few months trying to track down a set of 3 bars for my 94. I've got a 4bar headed engine on the stand, but just didn't want to deal with the plug angle. Every set of ready to go 3 bars were $800-900 and I couldn't see myself spending that when aluminum heads are just a bit more.
My current plan is to run a set of the Chinese AFR 185 Enforcer heads. $1300 assembled, there's other China heads on the market, but I have a little more faith in AFR to set these up a little better than some of the other brands out there.
