Used on 1600, 1750 and early 2L engines. Sometimes used as a less restrictive replacement on later 2L engines. No cracks and normal pitting except for an odd hole on the top of the #4 pipe. It doesn't go all the way through but needs to be weld-filled before it does. $55 plus shipping for the pair. About 15 lbs. shipped from 21740. I thought that these would fit in a large flat rate box but was mistaken so send me your zip code for a shipping quote.
