360 Exhaust Manifold Gasket

rollbar

I need to get set for the stock exhaust & NAPA is showing me this. Mine are in a straight line. I pulled it up for a 1974 4 wd Cherokee cause I have a 1974 engine. Now, R U suposed to cut these, that seems weird. :razz:

That be them. You break them at the perfs so you have one gasket for each end, and one for the center pair of ports. Bob tufcj

Thanks Bob, I'll order them tomorrow. Just looked weird. I'm a 258 guy & when I had my 304 I didn't need to do anything except rebuild the carb. 1. Since it's a '74 do I just say for that year or will all 360's be the same. 2. In the future when asking for parts.....refer to question 1. Thanks, Jim

Forgot to ask, what size bolts do I need for the stock exhaust manifolds.

All 360s are the same from 71-91. Gasket kits are the same for 304 - 401 with the exception of the head gaskets, so the 304 full gasket kit has a different number than the 360-401. Not sure on the length of the exhaust manifold bolts, but they are 3/8" bolts. Use a minimum grade 5 bolt, with a grade 5 washer. The bolts in a bin at most hardware stores are grade 2, they will fatigue/stretch and come loose pretty quickly in the heat/cool cycles of the exhaust. Check your heads, as some late model heads used 5/16" bolts in the front and rear holes. If they are 74, all the holes should be 3/8". Bob tufcj
