Urgent: Need Advice On 454 BBC Headers For 71 Nova

[71Nova454]

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
