Hard to go wrong for $175... Me personally, i wouldn't pull the heads off my car for the sole sake of swapping on ported heads, but if my motor was on an engine stand, and the heads on the motor had 75k+ miles on them, i'd deffinately dish out $175. Plus, i've heard nothing but good stuff and this dudes port work.
