No they dont suck. But I don't think you'll be able to use them. The oil feed line is taped into the block rite behind the exhaust manifold. It might not be possibly to tap in the same position(are the oil gallys the same from DE to DET?). The coolant feed line is taped rite behind the thermostat housing(this may be possible to do) but the coolant return is taped into the block near the oil feed line(DE-DET coolant galleys?). I don't think you want to be drilling and taping your block!
