Hi i just purchase a set of risers and manifolds for my 1998 4.3 liter but forgot to order the spacer question is no one around has ever heard of the 1 1/4 inch spacer so would the engine cowl shut with a 3 inch because in cant seem to find that spacer even on the internet. thanks blake sullivan

maybe they can clean out your old ones. perhaps they could use a pneumatic wire brush on the exhaust passage and clean out the water jackets with vinegar and scraping. a head shop can resurface the faces if they dont look like they will seal.
good luck
