I lol'ed....High EGTS are usually cause by Lean conditions or by Low timing. Which would probobly be the cause on yours. You're probobly seeing a boatload of KR and its killing timing. You dont have crap for mods go to a 3.8 pulley. Narrowband A/F gauge is worthless at Wideopen throttle reading. You also need to get plugs in your proper heat range. I run 103's but I have a decent list of mods Fwiw.
Further more High Exhaust temps can cause major expensive problems quickly
