402 BB exhaust manifold bolts? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Daves72'GMC · 12-02-2003, 10:12 PM

I just picked up my 402BB to rebuild and when the restorer took the engine out he broke off 2 of the 3 bolt studs on the exhaust manifold that bolt to the exhaust pipe on the right side by the starter. What size of bolts are they and where can I get new ones? and whats the best way to get the old studs out of the manifold?Thank you everyone

Agood exhaust shop should be able to replace the manifold stud's, unless you have a vise then you could go to an exhaust shop and but the new stud's to install yourself.. I tried it once, it was a pain in the a$$..

You can get them at any auto parts store. I have got them at Autozone in the HELP section. They come in packs of 3 with brass nuts. Wes.
