I’m trying to start the 327 in my 1957 NAPCO conversion project. I’m installing a temporary exhaust set up in order to break in the cam. I have aftermarket Rams horn exhaust manifolds with down pipes that are flared for the donut type seals. I’m searching for a torque value for the stud nuts that hold the assembly together. The studs are 3/8-16” into the flange and 3/8-24 on the long end. Any help would be very appreciated. I’m getting a little bleary eyed with all of the last minute gotchas!
Thank you,
Larry
