Have taken apart and rebuilt rusted counterweight for Flapper valve in right side Exhaust Manifold. Am ready to put back together.Question is:should I put the flapper plate back inside the Manifold and make It all work like original,or just put the Shaft thru without the Flapper Plate,and weld the shaft to the inside of the manifold with the Counterweight in the open position always??

For me, I would have to decide whether or not I needed it to warm up faster. With it closed, the exhaust gases go up and across the underside of intake. If you drive it alot in colder weather, you may want to leave it operational, or if you only drive it in a warmer climate, and drivability isn't/won't be a concern.

Blocked off the heat crossover and elimintated the flap; have no plan to drive my car when it's cold and don't want to compromise performance. Dave

With it out it'll destroy your gas mileage esp in cold weather (if that is a concern) & I'm gathering that it is not. To make it inop might tap the sides for 2 brass pipe plugs so in the future you could return it to OE if desired w some brass bushings plus the shaft/flap is a significant restriction. I am assuming these are HP ex manifolds

Thanks for response!I got some stainless washers, fitted 'em onto shaft after removing flapper,and welded washers on each side of shaft up against inside of Manifold.I now have slight bit of movement to Counterweight,so it looks like everythings as original,but no Flapper.Manifold is now installed..
