Do I need special intake gaskets for LT1 intake?

Or will any 88+ SBC intake gasket be fine? Also, bought the manifold on ebay and it comes with modified fuel rail/ accel FPR / and remote thermostat. Besides the return hoses from the thermo to the manifold, what else will I need?

Use 1979 and earlier Camaro intake gaskets if you want cheap. They don't have EGR ports in them.

D'oh, yeah, what he said. Don't want the EGR ports on there because the LT1 intake doesn't have em. You lose your EGR function when swapping to LT1 intake.

Might not be a good idea for you in Arizona, I hear they visually check for EGR. Look into getting the setup off an LT1 'vette. I believe they had an external EGR setup. All you need to do is make it APPEAR to be working, and then get a chip burned to disable EGR in the computer or you'll throw codes.
