manifold question, please help!!
 

Hi guys! So have a question, I was at junk yard a couple days ago looking for parts for my 86 n/a. Came across I believe a 85 12a that had racing beat header so i grabbed it. I know I have to do some modifications for it to fit, anyways I took my stock manifold off and noticed that the engine had the 2 main exhaust holes then a little port below. So if i was to get the racing beat header on is it safe to have that mini port (hole) covered by the rb header?

Mine is but I have removed all my emissions so in your case I wouldn't know for sure.

Humm alright, I've looked at the RB header for the 86 and I didnt see that third port so.

That port is used for air injection. You may need it to pass emissions, otherwise, it is unnecessary

No emissions in my state so I'm golden, thanks for the help guys

Wait! I just reread the above post... 12A engines are not as long as 13B engines, I am pretty sure the headers won't fit without some modifications. I misread the above post the first time. I thought the headers were on an 85 GSL (13B)
