Also it kind of overheats temp goes 3 notches above normal temp but never fully overheats once i start moving it cools down just want to fix small issue before it gets worse any advice would be great.

Check your brake fluid reservoir and see if its low. If so add fluid. You may need to "bleed" your brakes as well.

Check all four corners and make sure your individual wheel cylinders or brake lines are not leaking.

As for your overheating issue, it could be old/bad anti-freeze and perhaps you need to do a flush and fill with new correct antifreeze/water mixture. Your thermostat could be sticking and needs to be replaced. I'd start with those rather simple things first.  

The other three spark plug wires are up close to the firewall. Check out this YouTube video to give you idea of how to do it.

      I need help figuring out why my 400 is overheating
      It is a 1987 gen3 Fire-bird Formula (reFormulated) with a 1971 Pontiac 400 block casting #481988 bored .030 over with Keith Black dish pistons, crank has been turned .020/.020. Rotating assembly has been balanced, Number 16 heads with new valves and springs, 72cc cambers. Howard's CAM in.482 ex.470, true dual exhaust, new water pump with cast impeller, divider plate clearance set as close as possible to impeller. New 4 core aluminum radiator with 2 10 inch electric fans pulling air and 2 12 inch electric fans pushing air. A/C condenser removed to allow maximum air flow. Removed thermostat, still overheating. Installed a flow restrictor hoping the water was flowing to fast through the radiator for efficient heat transfer. No still HOT. New 180 degree thermostat. With each change it continued to overheat, although the time it takes to overheat varied. I really hope someone here has an idea what I am facing.
