Exhaust suggestions

Long story short, Iím tired of dealing with the issues that come along with headers. Looking to go with stock type manifold. Looking for suggestions on sites that have good exhaust manifolds for 396bbc.
Thank you

Re: Exhaust suggestions

Google is your friend. I am going to try and install the big block Corvette manifolds when I do the swap on my 69 short step. They look like they will work but I haven't started the swap yet.

What kind of issues? Im new to the scene and currently have some short tubes on my 307 that were on the truck when I got it. They are kind of crappy looking and dented to hell and back, so I was planning on replacing them with some long tubes eventually.

Re: Exhaust suggestions

Not to be contrary but my BB Blazer has an inexpensive Hedman set that were installed by the PO.. They have the ball & socket collector ends and soft copper gaskets at the cyl. heads. I've had the truck 5-6 years with no leaks & I drive it quite a bit. They're painted(ugly) and hang a little too low. I know they don't produce much performance gain...... but just saying they don't hafta be a P.I.T.A.

Re: Exhaust suggestions

Leak, hang to low, heat up the starter and always have to be carful with plug wires. I need to re-do the entire exhaust so I figured I would get away from long tube headers while I was at it.

Re: Exhaust suggestions

FWIW, I'll say that not all headers are created equal. There's inexpensive, then there's cheap, then there's high quality. Quality headers bring quality results, but expensive doesn't always mean quality. Some companies just have their cheap headers ceramic coated and slap on a big price tag. In other words, you get what you pay for. Thick flanges with good tube welds on both sides and machined head contact surfaces are a must, then I've discovered to use a light coat of copper infused orange RTV in conjunction with MLS gaskets or no gaskets at all, just the RTV. As for the collectors, stop fooling with 3-bolt flanges and gaskets and get V-band clamps for the ultimate gasketless seal.

However, if overall horsepower isn't the goal, then a nice set of stock manifolds will be fine. Look for a good used set or a NOS set, then have them gray or black ceramic coated by a reputable company and never worry with them again for many years.
