Headers vs 360 manifolds for 318

I hit my Milodon oil pan once, coming down from a jump,on dirt, a lil nose heavy,lol. Hard enough to crack it. After the repair work, I installed a skidplate. Good thing, cuz it is now a witness to my driving style,lol. Yeah I'm exaggerating a lil , it's not that beat-up...........
But I gotta tell you, when the oilpan hits dirt, for a split second,everything comes to a grinding halt. Then the suspension rebounds, pulls the pan up outta the dirt, and it's business as usual, until you stop in the pits for a look-see. This with 1.03 bars and very stiff shocks.
Then the track crew has to fill in the trench, and nobody brought a shovel, cuz no other competitor brought a V8 to the event, so they were not expecting mayhem..
I mighta won that day, if the dang dirt hadn't slowed me down so much..... I was mere seconds from winning. A couple of people still today, remember that big red flying fish.
So my advice is to not jump your car,lol.
