ARH is building us some race headers with no smog pump provisions. When I install them I'm going to remove the smog pump (it's a race car). Are there some type of block off plates that I'll need for the engine and if so where do they go and where do I buy them?

Thanks.

The only block off plates you need are for the AIR tube flanges on the headers, but you said they're making them for you without those so you shouldn't need the plates.
There is also a little vacuum line that runs to the AIR pump that you should cap off if you're completely removing the pump from the vehicle.

Thank you. That's sounds easy enough. I've done this on an LT1 before and you had to put a block off plate on the back on the intake.
