could someone please tell me the torque specs for my 302 exhaust manifolds. thanks

 

18 to 24 ft lbs. according to ford , that is manifold to head.

 

I usually torque them to 20 ft lbs thats good enough.

 

do they need to be re torqued?

 

Following up on a 16+ year old thread...

Ford's manifold bolts have captive lock washers, designed to keep the bolts tight. But it doesn't hurt to check them after a couple of heat/cool cycles.

If you use the hardware included with most aftermarket headers, you should definitely check them periodically.

I've never tried those "stage 9" bolts with the C-clips on the heads, but their design prevents the bolts from turning after you install them. But quite often, the header flanges don't prvide enought room to use them.
