Anyone know torque for headers?

LOCASH · 01-11-2001, 01:23 PM

I have Mac shorties and I bought new gaskets because they were leaking. Does anyone know what I should torque them to? I am using the Earl's gaskets.

I just tightened my header bolts without torquing them. I know of 3 other cars with after market headers, and none of them were torqued to certain specs. Just make sure they are good and tight, and check them after a few days of driving to make sure none are loose.

Tight. Just kidding....tighten them down snug and drive the car for a while, get it nice and hot, and then let it cool and re-check the bolts. They have a tendancy to work their way loose.
