Exhaust Gas Recirculation.

 

To expand on the previous post, those are for the EGR fittings on the 307. You need to plug them with pipe plugs if you are not using EGR.

 

If the cap on the driver's side has a good seal, then you don't necessarily need to cap them. That just lets to two sides breathe into each other. Not great, but not horrible either.

 

Thanks for the responses!!!!
It didn't look right to me but for the price I wasn't about to pass on it!!!!!

 

Do the holes go in to the cross over?What goes in them if you are using an EGR?You are talking about the two holes under the carb right?My Holley had one I welded it shut,but would still like more about it.No body could tell me anything.
