Intake gaskets

Run "the right stuff" gasket maker, it can do up to 1/4 inch gap, if its more than 1/4, use 2 applications after first dries. Cork always worked for me. It was always a little to thick but the bolts cinched it down tight.
"Apply a continuous 1/8″ to 1/4″ bead to one surface, surrounding all bolt holes. Assemble parts within five minutes, tightening bolts to recommended torque levels. Material will fill any surface imperfection. Equipment can be returned to service immediately."
