Aftermarket Header installation problems - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi

I am in the midst of restoring my grandfathers pick up. I left the six (250) in for the sake of memories. I wanted a little more out of it so in addition to an overhaul, bigger cam, offy intake, and Holley 390, I installed a set of headers. The problem is that the original fasteners don't fit with the aftermarket headers and intake. I used large washers and bolts instead and still the headers pull free and have made a nasty spot on my new paint job. How do some of ya'll have your headers and intakes fastened?

Thanks a bunch!

Welcome to the site. you will need to get header bolts preferably with the lock ring to hold in place. Standard bolts will vibrate lose.

The headers should have come with proper bolts/hardware. BTW,there are no factory headers. All headers are aftermarket

Thank you both, I will run down to NAPA and see if I can get a set and give it a try. Thanks
