Urgent: Need Advice On 454 BBC Headers For 71 Nova

[92646]

I bought my headers coated from Hooker and the coating was not as good as I have seen on other headers. Be careful with the instalation because the coating can scratch very easily. I left the wrapping on the headers during the instalation and that helped. You might want to buy the header bolts with the clips that keep the bolts from backing out. I think they are called spec 8 or a name close to that. You might also check with Jet hot because they sell new coated headers at a good price.

hey Michael, I agree with Orange County Mark. The coatings on the Hooker SC's don't last as long. I would buy the cheaper set of Hookers and get them coated yourself. Different header tubing size helps determine the fit also. You don't need Pro Stock sized tubes for the street. I love you west coast guys and especially your good used sheetmetal!!! Sam

I have Jet Hot coating on the headers on my '70 Camaro and it’s not everything I've expect. Make sure there is no moisture in the garage where the car is and also take really careful care of the headers. I think Jet Hot advises you use some sort of polish for the headers. Make sure you follow their directions meticulously otherwise they will rust (Slowly).

I would just powder coat them flat white.

Gotta agree with the fact that Hooker's coating is terrible and doubles the price of the headers. I bought my set new coated from Hooker and within a year they were just peppered with surface rust. I'd avoid the Super Comps and just get the #2457 regular Hooker Comp headers and a couple cans of VHT Hi-Temp paint. Pick your own color but I like traditional white!

Thanks for all the replies so far fellas...Going to talk to my dad tonight and pass along this info to him.

so what size tubing should he be looking for?
Anyone know what size tubing the Hooker Comp #2457 are?

I doubt he's looking to get the ceramic coated ones as he's looking for something durable, that'll provide good performance and will just bolt on without any dimpling, etc.

If possible he's wanting to do this without lifting the motor...I'm not sure whether the motor mounts are for the big block or small...From what I've read that can make all the difference on the clearance issues.

Thanks again,

Michael

Hooker Comp #2457 are 2" primary tubes...

Those Hooker #2457's are 2.00 inch primaries, which is a great size for a big block. As long as you make the very small investment in the proper frame mounts, you won't have to take a hammer anywhere near those nice new headers. Spark plug clearance is great and you they are a very easy install without having to lift the motor to put them in place. Great header, great price, easy install. You're all set.

And this just goes to show why this site is such a cool place to hang out...LOTS of good info here

Not to sound contrary to what's already been discussed, but a 2" header is a bit large for a relatively mild street BBC. A 1 3/4" header will easily support well over 500 HP, usually with the added benefits of more low end torque, plus they almost always fit better and offer better spark plug access than the larger tubes do. I haven't priced any lately, but they used to be considerably more affordable than the larger tubes as well.

Just something to think about.
