He could be “playing dumb” or just doesn’t have a clue. Even if they are 1.88, they look clean from that picture, if the intake is good and the 318 heads are nice that’s good deal...get them for less even better! (Never understand why when selling something people only post 1 picture??) One thing I like about buying parts in person is they usually always have other parts they’ll sell and then you can get them bundled together for a better deal! I’ve had people come here to buy 1 thing and left with a bunch of extras!
