New Notch-current Set Up Opinions

Purchased a notch about a month ago pulled the engine and just got it back on the road(oil pan change). Here is a list of mods, the injector size is the main question I have.

Holly Heads, Holly systemax upper and lower, Holly 70mm TB, CAI, 30lb inj , BBK Equals, X pipe, Flowmasters, 373 gears, 5 lug conv(rear drums ), Subframe connectors, Bilstien shocks, AC Delete, Bigger Alternator.

Seems to run rich, should I put 24lb injectors on? If so what will it do for performance and gas milage? What mods should I do next?

Also I had a tube that ran from the back of the left head connected to the right head then caped off on the right side. I assumed this was smog but still unsure. While the motor was out I removed this line and used 2" washers to cover the holes. should these holes be connected for any reason?

Thanks!

Flipping them is a good idea, I may do that. The washer seems to be leaking a little so I must need some thicker metal to hold the pressure. As far as the holly heads I cannot say yet. I need to dyne the car and tune it to compare. Looks like the guy liked holly, but it is nice he stuck with one brand.

Good catch THANKS! I'm curious to what internals it may have. Doesn't seem like it has a cam, but it may have a mild one. I am looking forward to seeing what smaller injectors do. Exhuast smells very rich.
