Ive got a '65 Austin Healey sprite that I have put a streetported 12a into. Ive got a couple of options on intake manifolds that I could use some recommendations / insight on. I am planning on running a SR Racing modified nikki with either of these options.

Option 1: I picked up this manifold off of ebay awhile back. A previous owner ported the manifold and mated an adapter plate to it to allow a holley 4 barrel carb to be mounted to it. I have removed the adapter plate from it and it looks like I can go back to mounting the nikki carb to it with minimal issues. The plus is that its already cleaned up and has all of the emissions crud removed and blocked off.

Option 2: I believe is a bone stock manifold with no modifications to it (I think)

Any thoughts? Anyone know what the option 1 manifold came off of?
