exhaust manifold leak

I agree with Mitch. I've been through this myself. New intake, exhaust, studs, nuts, washers, gland rings with copper gaskets & no sealant (unless you want to risk getting some in your valves & oil pump screen). Torque to 45 pounds and re-torque after compete cool down (next day) until you get no more out of them (5-10 times?). It seems to be the best way... and the cheapest in the long run, if time is money.

if you re-read Mitch #8 he does not say use 45 ft-lbs (or lb-ft if you want to be an engineer).

You are not torquing a cyl head here.....
I know a guy who just broke an ear off because he over-torqued...so, have at it

Indiana,
They WON'T twist off @ 45 Ft Lbs, they're the SAME size as the HEAD studs "Someone" said the High Temp Exhaust Sealer would blow or burn out, IT WON'T I only ever recommend stuff that has worked for me, personally. Take it or leave it!

I saw a Paul Shinn video on replacing the exhaust manifold gasket. He uses split rings, high temp sealant on both sides of the copper shrouded gasket, domed washers ( dome facing out) and 45 ft-lbs of torque. His video is on YOUTUBE. He also lets everything set overnight and checks torque again setting the wrench to 40 ft-lbs. Watch his videos...he is very enthusiastic about Model As and is an excellent mechanic like us.
