The Stovebolt Site Forums The Shop Area Engine Shop 235 exhaust manifold gasket advice, PLEASE

Replaced exhaust manifold gasket last week-cannot get manifold gasket to seal-Several exhaust leaks.
Used Felpro gasket.
Plan:
Remove manifold;
Have manifold mating surfaces machined;
Clean head;
Replace gasket and manifold.
QUESTIONS:
Type of gasket recommended?;
Gasket sealant recommended?;
Torque specs for manifold bolts?
Thanks

Did you also replace the gasket at the Heat box?

Leave everything loose and torque in sequence.




I did take my manifold to a machinist
Just a dab of sealant to hold in place , but none is necessary.

Used felpro gaskets

Thanks for the reply.
Did not replace heat box gasket..one of the only places it doesn't leak!
Will replace HBG before shop work.
Have new Felpros....
Thanks for the torque requirements,
Jones

Make sure the intake manifold alignment rings aren't jamming up the fit.

Like Leon said, make sure the alignment rings went in straight.
If you can not push the manifold up tight to the head with out the help of the bolts STOP. A lot of the time the exhaust manifold warps up at the ends. If this happens the alignment studs on each end keep the manifold out of position for the intake rings to line up. A lot of the times I have to leave out the end alignment studs.
